An abstract class providing a RowSet object with its basic functionality.
The basic functions include having properties and sending event notifications,
which all JavaBeansTM components must implement.

1.0 Overview
The BaseRowSet class provides the core functionality
for all RowSet implementations,
and all standard implementations may use this class in combination with
one or more RowSet interfaces in order to provide a standard
vendor-specific implementation.  To clarify, all implementations must implement
at least one of the RowSet interfaces (JdbcRowSet,
CachedRowSet, JoinRowSet, FilteredRowSet,
or WebRowSet). This means that any implementation that extends
the BaseRowSet class must also implement one of the RowSet
interfaces.

The BaseRowSet class provides the following:


Properties
    

    
Fields for storing current properties
    
Methods for getting and setting properties
    
 

Event notification

A complete set of setter methods for setting the parameters in a
     RowSet object's command
 

 Streams
 

 
Fields for storing stream instances
 
Constants for indicating the type of a stream
 
 


2.0 Setting Properties
All rowsets maintain a set of properties, which will usually be set using
a tool.  The number and kinds of properties a rowset has will vary,
depending on what the RowSet implementation does and how it gets
its data.  For example,
rowsets that get their data from a ResultSet object need to
set the properties that are required for making a database connection.
If a RowSet object uses the DriverManager facility to make a
connection, it needs to set a property for the JDBC URL that identifies the
appropriate driver, and it needs to set the properties that give the
user name and password.
If, on the other hand, the rowset uses a DataSource object
to make the connection, which is the preferred method, it does not need to
set the property for the JDBC URL.  Instead, it needs to set the property
for the logical name of the data source along with the properties for
the user name and password.

NOTE:  In order to use a DataSource object for making a
connection, the DataSource object must have been registered
with a naming service that uses the Java Naming and Directory
InterfaceTM (JNDI) API.  This registration
is usually done by a person acting in the capacity of a system administrator.

3.0 Setting the Command and Its Parameters
When a rowset gets its data from a relational database, it executes a command (a query)
that produces a ResultSet object.  This query is the command that is set
for the RowSet object's command property.  The rowset populates itself with data by reading the
data from the ResultSet object into itself. If the query
contains placeholders for values to be set, the BaseRowSet setter methods
are used to set these values. All setter methods allow these values to be set
to null if required.

The following code fragment illustrates how the
CachedRowSetTM
object crs might have its command property set.  Note that if a
tool is used to set properties, this is the code that the tool would use.
   crs.setCommand("SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
                  "WHERE CREDIT_LIMIT > ? AND REGION = ?");


In this example, the values for CREDIT_LIMIT and
REGION are placeholder parameters, which are indicated with a
question mark (?).  The first question mark is placeholder parameter number
1, the second question mark is placeholder parameter number
2, and so on.  Any placeholder parameters must be set with
values before the query can be executed. To set these
placeholder parameters, the BaseRowSet class provides a set of setter
methods, similar to those provided by the PreparedStatement
interface, for setting values of each data type.  A RowSet object stores the
parameter values internally, and its execute method uses them internally
to set values for the placeholder parameters
before it sends the command to the DBMS to be executed.

The following code fragment demonstrates
setting the two parameters in the query from the previous example.
   crs.setInt(1, 5000);
   crs.setString(2, "West");

If the execute method is called at this point, the query
sent to the DBMS will be:
   "SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
                  "WHERE CREDIT_LIMIT > 5000 AND REGION = 'West'"

NOTE: Setting Array, Clob, Blob and
Ref objects as a command parameter, stores these values as
SerialArray, SerialClob, SerialBlob
and SerialRef objects respectively.
4.0 Handling of Parameters Behind the Scenes
NOTE: The BaseRowSet class provides two kinds of setter methods,
those that set properties and those that set placeholder parameters. The setter
methods discussed in this section are those that set placeholder parameters.

The placeholder parameters set with the BaseRowSet setter methods
are stored as objects in an internal Hashtable object.
Primitives are stored as their Object type. For example, byte
is stored as Byte object, and int is stored as
an Integer object.
When the method execute is called, the values in the
Hashtable object are substituted for the appropriate placeholder
parameters in the command.

A call to the method getParams returns the values stored in the
Hashtable object as an array of Object instances.
An element in this array may be a simple Object instance or an
array (which is a type of Object). The particular setter method used
determines whether an element in this array is an Object or an array.

The majority of methods for setting placeholder parameters take two parameters,
 with the first parameter
indicating which placeholder parameter is to be set, and the second parameter
giving the value to be set.  Methods such as setInt,
setString, setBoolean, and setLong fall into
this category.  After these methods have been called, a call to the method
getParams will return an array with the values that have been set. Each
element in the array is an Object instance representing the
values that have been set. The order of these values in the array is determined by the
int (the first parameter) passed to the setter method. The values in the
array are the values (the second parameter) passed to the setter method.
In other words, the first element in the array is the value
to be set for the first placeholder parameter in the RowSet object's
command. The second element is the value to
be set for the second placeholder parameter, and so on.

Several setter methods send the driver and DBMS information beyond the value to be set.
When the method getParams is called after one of these setter methods has
been used, the elements in the array will themselves be arrays to accommodate the
additional information. In this category, the method setNull is a special case
because one version takes only
two parameters (setNull(int parameterIndex, int SqlType)). Nevertheless,
it requires
an array to contain the information that will be passed to the driver and DBMS.  The first
element in this array is the value to be set, which is null, and the
second element is the int supplied for sqlType, which
indicates the type of SQL value that is being set to null. This information
is needed by some DBMSs and is therefore required in order to ensure that applications
are portable.
The other version is intended to be used when the value to be set to null
is a user-defined type. It takes three parameters
(setNull(int parameterIndex, int sqlType, String typeName)) and also
requires an array to contain the information to be passed to the driver and DBMS.
The first two elements in this array are the same as for the first version of
setNull.  The third element, typeName, gives the SQL name of
the user-defined type. As is true with the other setter methods, the number of the
placeholder parameter to be set is indicated by an element's position in the array
returned by getParams.  So, for example, if the parameter
supplied to setNull is 2, the second element in the array
returned by getParams will be an array of two or three elements.

Some methods, such as setObject and setDate have versions
that take more than two parameters, with the extra parameters giving information
to the driver or the DBMS. For example, the methods setDate,
setTime, and setTimestamp can take a Calendar
object as their third parameter.  If the DBMS does not store time zone information,
the drivern uses the Calendar object to construct the Date,
Time, or Timestamp object being set. As is true with other
methods that provide additional information, the element in the array returned
by getParams is an array instead of a simple Object instance.

The methods setAsciiStream, setBinaryStream,
setCharacterStream, and setUnicodeStream (which is
deprecated, so applications should use getCharacterStream instead)
take three parameters, so for them, the element in the array returned by
getParams is also an array.  What is different about these setter
methods is that in addition to the information provided by parameters, the array contains
one of the BaseRowSet constants indicating the type of stream being set.

NOTE: The method getParams is called internally by
RowSet implementations extending this class; it is not normally called by an
application programmer directly.
5.0 Event Notification
The BaseRowSet class provides the event notification
mechanism for rowsets.  It contains the field
listeners, methods for adding and removing listeners, and
methods for notifying listeners of changes.

A listener is an object that has implemented the RowSetListener interface.
If it has been added to a RowSet object's list of listeners, it will be notified
 when an event occurs on that RowSet object.  Each listener's
implementation of the RowSetListener methods defines what that object
will do when it is notified that an event has occurred.

There are three possible events for a RowSet object:

the cursor moves
an individual row is changed (updated, deleted, or inserted)
the contents of the entire RowSet object  are changed


The BaseRowSet method used for the notification indicates the
type of event that has occurred.  For example, the method
notifyRowChanged indicates that a row has been updated,
deleted, or inserted.  Each of the notification methods creates a
RowSetEvent object, which is supplied to the listener in order to
identify the RowSet object on which the event occurred.
What the listener does with this information, which may be nothing, depends on how it was
implemented.

6.0 Default Behavior
A default BaseRowSet object is initialized with many starting values.
The following is true of a default RowSet instance that extends
the BaseRowSet class:

  
Has a scrollable cursor and does not show changes
      made by others.
  
Is updatable.
  
Does not show rows that have been deleted.
  
Has no time limit for how long a driver may take to
      execute the RowSet object's command.
  
Has no limit for the number of rows it may contain.
  
Has no limit for the number of bytes a column may contain. NOTE: This
  limit applies only to columns that hold values of the
  following types:  BINARY, VARBINARY,
  LONGVARBINARY, CHAR, VARCHAR,
  and LONGVARCHAR.
  
Will not see uncommitted data (make "dirty" reads).
  
Has escape processing turned on.
  
Has its connection's type map set to null.
  
Has an empty Vector object for storing the values set
      for the placeholder parameters in the RowSet object's command.


If other values are desired, an application must set the property values
explicitly. For example, the following line of code sets the maximum number
of rows for the CachedRowSet object crs to 500.
   crs.setMaxRows(500);

Methods implemented in extensions of this BaseRowSet class must throw an
SQLException object for any violation of the defined assertions.  Also, if the
extending class overrides and reimplements any BaseRowSet method and encounters
connectivity or underlying data source issues, that method may in addition throw an
SQLException object for that reason.

Sets the Url property for this RowSet object
to the given String object and sets the dataSource name
property to null. The Url property is a
JDBC URL that is used when
the connection is created using a JDBC technology-enabled driver
("JDBC driver") and the DriverManager.
The correct JDBC URL for the specific driver to be used can be found
in the driver documentation.  Although there are guidelines for for how
a JDBC URL is formed,
a driver vendor can specify any String object except
one with a length of 0 (an empty string).

Setting the Url property is optional if connections are established using
a DataSource object instead of the DriverManager.
The driver will use either the URL property or the
dataSourceName property to create a connection, whichever was
specified most recently. If an application uses a JDBC URL, it
must load a JDBC driver that accepts the JDBC URL before it uses the
RowSet object to connect to a database.  The RowSet
object will use the URL internally to create a database connection in order
to read or write data.

Sets the fetch size for this RowSet object to the given number of
rows.  The fetch size gives a JDBC technology-enabled driver ("JDBC driver")
a hint as to the
number of rows that should be fetched from the database when more rows
are needed for this RowSet object. If the fetch size specified
is zero, the driver ignores the value and is free to make its own best guess
as to what the fetch size should be.

A RowSet object inherits the default properties of the
ResultSet object from which it got its data.  That
ResultSet object's default fetch size is set by
the Statement object that created it.

This method applies to a RowSet object only while it is
connected to a database using a JDBC driver.
For connected RowSet implementations such as
JdbcRowSet, this method has a direct and immediate effect
on the underlying JDBC driver.

A RowSet object may use this method at any time to change
its setting for the fetch size.

For RowSet implementations such as
CachedRowSet, which operate in a disconnected environment,
the SyncProvider object being used
may leverage the fetch size to poll the data source and
retrieve a number of rows that do not exceed the fetch size and that may
form a subset of the actual rows returned by the original query. This is
an implementation variance determined by the specific SyncProvider
object employed by the disconnected RowSet object.

Params:
rows – the number of rows to fetch; 0 to let the
       driver decide what the best fetch size is; must not be less
       than 0 or more than the maximum number of rows
       allowed for this RowSet object (the number returned by a call to the method getMaxRows)

Sets the designated parameter to SQL NULL.
Note that the parameter's SQL type must be specified using one of the
type codes defined in java.sql.Types.  This SQL type is
specified in the second parameter.

Note that the second parameter tells the DBMS the data type of the value being
set to NULL. Some DBMSs require this information, so it is required
in order to make code more portable.

The parameter value set by this method is stored internally and
will be supplied as the appropriate parameter in this RowSet
object's command when the method execute is called.
Methods such as execute and populate must be
provided in any class that extends this class and implements one or
more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method
as it is undefined in this class.

Calls made to the method getParams after this version of
setNull
has been called will return an Object array containing the parameter values that
have been set.  In that array, the element that represents the values
set with this method will itself be an array. The first element of that array
is null.
The second element is the value set for sqlType.
The parameter number is indicated by an element's position in the array
returned by the method getParams,
with the first element being the value for the first placeholder parameter, the
second element being the value for the second placeholder parameter, and so on.
In other words, if the second placeholder parameter is being set to
null, the array containing it will be the second element in
the array returned by getParams.

Note that because the numbering of elements in an array starts at zero,
the array element that corresponds to placeholder parameter number
parameterIndex is parameterIndex -1.
Params:
parameterIndex – the ordinal number of the placeholder parameter
       in this RowSet object's command that is to be set.
       The first parameter is 1, the second is 2, and so on; must be
       1 or greater
sqlType – an int that is one of the SQL type codes defined in the class Types. If a non-standard sqlType is supplied, this method will not throw a
       SQLException. This allows implicit support for
       non-standard SQL types.
Throws:
SQLException – if a database access error occurs or the given
       parameter index is out of bounds

Sets the designated parameter to SQL NULL.
Although this version of the  method setNull is intended
for user-defined
and REF parameters, this method may be used to set a null
parameter for any JDBC type. The following are user-defined types:
STRUCT, DISTINCT, and JAVA_OBJECT,
and named array types.
Note: To be portable, applications must give the
SQL type code and the fully qualified SQL type name when specifying
a NULL user-defined or REF parameter.
In the case of a user-defined type, the name is the type name of
the parameter itself.  For a REF parameter, the name is
the type name of the referenced type.  If a JDBC technology-enabled
driver does not need the type code or type name information,
it may ignore it.

If the parameter does not have a user-defined or REF type,
the given typeName parameter is ignored.

The parameter value set by this method is stored internally and
will be supplied as the appropriate parameter in this RowSet
object's command when the method execute is called.

Sets the designated parameter to the given

which will have the specified number of bytes.
The contents of the stream will be read and sent to the database.
This method throws an SQLException object if the number of bytes
read and sent to the database is not equal to length.

When a very large ASCII value is input to a LONGVARCHAR
parameter, it may be more practical to send it via a
java.io.InputStream object. A JDBC technology-enabled
driver will read the data from the stream as needed until it reaches
end-of-file. The driver will do any necessary conversion from ASCII to
the database CHAR format.

Java stream object or your own subclass that implements the
standard interface.

will be supplied as the appropriate parameter in this RowSet
object's command when the method execute is called.
Methods such as execute and populate must be
provided in any class that extends this class and implements one or
more of the standard JSR-114 RowSet interfaces.

Note: JdbcRowSet does not require the populate method
as it is undefined in this class.

Calls made to the method getParams after setAsciiStream
has been called will return an array containing the parameter values that
have been set.  The element in the array that represents the values
set with this method will itself be an array. The first element of that array
is the given java.io.InputStream object.
The second element is the value set for length.
The third element is an internal BaseRowSet constant
specifying that the stream passed to this method is an ASCII stream.
The parameter number is indicated by an element's position in the array
returned by the method getParams,
with the first element being the value for the first placeholder parameter, the
second element being the value for the second placeholder parameter, and so on.
In other words, if the input stream being set is the value for the second
placeholder parameter, the array containing it will be the second element in
the array returned by getParams.

Note that because the numbering of elements in an array starts at zero,
the array element that corresponds to placeholder parameter number
parameterIndex is element number parameterIndex -1.
Params:
parameterIndex – the ordinal number of the placeholder parameter
       in this RowSet object's command that is to be set.
       The first parameter is 1, the second is 2, and so on; must be
       1 or greater
x – the Java input stream that contains the ASCII parameter value
length – the number of bytes in the stream. This is the number of bytes
      the driver will send to the DBMS; lengths of 0 or less are
      are undefined but will cause an invalid length exception to be
      thrown in the underlying JDBC driver.
Throws:
SQLException – if an error occurs, the parameter index is out of bounds,
      or when connected to a data source, the number of bytes the driver reads
      and sends to the database is not equal to the number of bytes specified
      in length

Sets the designated parameter to an Object in the Java
programming language. The second parameter must be an
Object type.  For integral values, the
java.lang equivalent
objects should be used. For example, use the class Integer
for an int.

The driver converts this object to the specified
target SQL type before sending it to the database.
If the object has a custom mapping (is of a class implementing
SQLData), the driver should call the method
SQLData.writeSQL to write the object to the SQL
data stream. If, on the other hand, the object is of a class
implementing Ref, Blob, Clob,
Struct, or Array,
the driver should pass it to the database as a value of the
corresponding SQL type.

Note that this method may be used to pass database-
specific abstract data types.

The parameter value set by this method is stored internally and
will be supplied as the appropriate parameter in this RowSetexecute is called.
Methods such as execute and populate must be
provided in any class that extends this class and implements one or
more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method
as it is undefined in this class.

Calls made to the method getParams after this version of
setObject
has been called will return an array containing the parameter values that
have been set.  In that array, the element that represents the values
set with this method will itself be an array. The first element of that array
is the given Object instance, and the
second element is the value set for targetSqlType.  The
third element is the value set for scale, which the driver will
ignore if the type of the object being set is not
java.sql.Types.NUMERIC or java.sql.Types.DECIMAL.
The parameter number is indicated by an element's position in the array
returned by the method getParams,
with the first element being the value for the first placeholder parameter, the
second element being the value for the second placeholder parameter, and so on.
In other words, if the object being set is the value for the second
placeholder parameter, the array containing it will be the second element in
the array returned by getParams.

Note that because the numbering of elements in an array starts at zero,
the array element that corresponds to placeholder parameter number
parameterIndex is element number parameterIndex -1.
Params:
parameterIndex – the ordinal number of the placeholder parameter
       in this RowSet object's command that is to be set.
       The first parameter is 1, the second is 2, and so on; must be
       1 or greater
x – the Object containing the input parameter value;
       must be an Object type
targetSqlType – the SQL type (as defined in java.sql.Types)
       to be sent to the database. The scale argument may
       further qualify this type. If a non-standard targetSqlType
       is supplied, this method will not throw a SQLException.
       This allows implicit support for non-standard SQL types.
scale – for the types java.sql.Types.DECIMAL and
       java.sql.Types.NUMERIC, this is the number
       of digits after the decimal point.  For all other types, this

Sets the designated parameter to the given Ref object in
the Java programming language.  The driver converts this to an SQL
REF value when it sends it to the database. Internally, the
Ref is represented as a SerialRef to ensure
serializability.

The parameter value set by this method is stored internally and
will be supplied as the appropriate parameter in this RowSet
object's command when the method execute is called.
Methods such as execute and populate must be
provided in any class that extends this class and implements one or
more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method
as it is undefined in this class.

After this method has been called, a call to the
method getParams
will return an object array of the current command parameters, which will
include the Ref object set for placeholder parameter number
parameterIndex.
Note that because the numbering of elements in an array starts at zero,
the array element that corresponds to placeholder parameter number
parameterIndex is element number parameterIndex -1.
Params:
parameterIndex – the ordinal number of the placeholder parameter
       in this RowSet object's command that is to be set.
       The first parameter is 1, the second is 2, and so on; must be
       1 or greater
ref – a Ref object representing an SQL REF
        value; cannot be null
Throws:
SQLException – if an error occurs; the parameter index is out of
        bounds or the Ref object is null; or
        the Ref object returns a null base type
        name.

Sets the designated parameter to the given
java.sql.Timestamp object.  The driver converts this
to an SQL TIMESTAMP value when it sends it to the database.

When the DBMS does not store time zone information, the driver will use
the given Calendar object to construct the SQL TIMESTAMP
value to send to the database. With a
Calendar object, the driver can calculate the timestamp
taking into account a custom time zone.  If no Calendar
object is specified, the driver uses the time zone of the Virtual Machine
that is running the application.

The parameter value set by this method is stored internally and
will be supplied as the appropriate parameter in this RowSet
object's command when the method execute is called.
Methods such as execute and populate must be
provided in any class that extends this class and implements one or
more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method
as it is undefined in this class.

Calls made to the method getParams after this version of
setTimestamp
has been called will return an array containing the parameter values that
have been set.  In that array, the element that represents the values
set with this method will itself be an array. The first element of that array
is the given java.sql.Timestamp object.
The second element is the value set for cal.
The parameter number is indicated by an element's position in the array
returned by the method getParams,
with the first element being the value for the first placeholder parameter, the
second element being the value for the second placeholder parameter, and so on.
In other words, if the timestamp being set is the value for the second
placeholder parameter, the array containing it will be the second element in
the array returned by getParams.

Note that because the numbering of elements in an array starts at zero,
the array element that corresponds to placeholder parameter number
parameterIndex is parameterIndex -1.
Params:
parameterIndex – the ordinal number of the placeholder parameter
       in this RowSet object's command that is to be set.
       The first parameter is 1, the second is 2, and so on; must be

Retrieves an array containing the parameter values (both Objects and
primitives) that have been set for this
RowSet object's command and throws an SQLException object
if all parameters have not been set.   Before the command is sent to the
DBMS to be executed, these parameters will be substituted
for placeholder parameters in the  PreparedStatement object
that is the command for a RowSet implementation extending
the BaseRowSet class.

Each element in the array that is returned is an Object instance
that contains the values of the parameters supplied to a setter method.
The order of the elements is determined by the value supplied for
parameterIndex.  If the setter method takes only the parameter index
and the value to be set (possibly null), the array element will contain the value to be set
(which will be expressed as an Object).  If there are additional
parameters, the array element will itself be an array containing the value to be set
plus any additional parameter values supplied to the setter method. If the method
sets a stream, the array element includes the type of stream being supplied to the
method. These additional parameters are for the use of the driver or the DBMS and may or
may not be used.

NOTE: Stored parameter values of types Array, Blob,
Clob and Ref are returned as SerialArray,

This version of the method setNull should
be used for user-defined types and REF type parameters.  Examples
of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and

a NULL user-defined or REF parameter.  In the case of a user-defined type
the name is the type name of the parameter itself.  For a REF
parameter, the name is the type name of the referenced type.  If
a JDBC driver does not need the type code or type name information,

sent to the server as a BLOB.  When the setBinaryStream method is used,
the driver may have to do extra work to determine whether the parameter
data should be sent to the server as a LONGVARBINARY or a BLOB
Params:
