package org.omg.CORBA;


An object used in Request operations to
describe the exceptions that can be thrown by a method.  It maintains a
modifiable list of TypeCodes of the exceptions.


The following code fragment demonstrates creating
an ExceptionList object:

   ORB orb = ORB.init(args, null);
   org.omg.CORBA.ExceptionList excList = orb.create_exception_list();


The variable excList represents an ExceptionList
object with no TypeCode objects in it.


To add items to the list, you first create a TypeCode object
for the exception you want to include, using the ORB method
create_exception_tc.  Then you use the ExceptionList
method add to add it to the list.
The class ExceptionList has a method for getting
the number of TypeCode objects in the list, and  after
items have been added, it is possible to call methods for accessing
or deleting an item at a designated index.

Since:  JDK1.2

Retrieves the number of TypeCode objects in this

Adds a TypeCode object describing an exception

Returns the TypeCode object at the given index.  The first

Params:

Removes the TypeCode object at the given index.
Note that the indices of all the TypeCoded objects
following the one deleted are shifted down by one.

Params:
