   Moves the cursor the specified number of rows from the current
position, with a positive number moving it forward and a
negative number moving it backward.

If the number is positive, the cursor moves the specified number of
rows toward the end of the rowset, starting at the current row.
For example, the following command, in which
crs is a CachedRowSetImpl object with 100 rows,
moves the cursor forward four rows from the current row.  If the
current row is 50, the cursor would move to row 54.

   crs.relative(4);
 

If the number is negative, the cursor moves back toward the beginning
the specified number of rows, starting at the current row.
For example, calling the method
absolute(-1) positions the cursor on the last row,
absolute(-2) moves it on the next-to-last row, and so on.
If the CachedRowSetImpl object crs has five rows,
the following command moves the cursor to the fourth-to-last row, which
in the case of a  rowset with five rows, is also the second row
from the beginning.

   crs.absolute(-4);
 
If the number specified is larger than the number of rows, the cursor
will move to the position after the last row. If the number specified
would move the cursor one or more rows before the first row, the cursor
moves to the position before the first row. In both cases, this method
throws an SQLException.

Note: Calling absolute(1) is the same as calling the
method first().  Calling absolute(-1) is the
same as calling last().  Calling relative(0)
is valid, but it does not change the cursor position.
Params: rows – an int indicating the number of rows to move
            the cursor, starting at the current row; a positive number
            moves the cursor forward; a negative number moves the cursor
            backward; must not move the cursor past the valid
            rows

   Moves the cursor for this CachedRowSetImpl object
to the insert row.  The current row in the rowset is remembered
while the cursor is on the insert row.

The insert row is a special row associated with an updatable
rowset.  It is essentially a buffer where a new row may
be constructed by calling the appropriate updateXXX
methods to assign a value to each column in the row.  A complete
row must be constructed; that is, every column that is not nullable
must be assigned a value.  In order for the new row to become part
of this rowset, the method insertRow must be called
before the cursor is moved back to the rowset.

Only certain methods may be invoked while the cursor is on the insert
row; many methods throw an exception if they are called while the
cursor is there.  In addition to the updateXXX
and insertRow methods, only the getXXX methods
may be called when the cursor is on the insert row.  A getXXX
method should be called on a column only after an updateXXX
method has been called on that column; otherwise, the value returned is
undetermined.

     * The checking can will done in the evaluate function which is implemented
     * in the class that implements the Predicate interface. So the checking
     * can vary from one implementation to another.
     *
     * Some additional points here on the following:
     * 1. updateBytes()     - since the evaluate function takes Object as parameter
     *                        a String is constructed from the byte array and would
     *                        passed to the evaluate function.
     * 2. updateXXXstream() - here it would suffice to pass the stream handle
     *                        to the evaluate function and the implementation
     *                        of the evaluate function can do the comparison
     *                        based on the stream and also type of data.
