public abstract class ExceptionList extends Object
Request
operations to
describe the exceptions that can be thrown by a method. It maintains a
modifiable list of TypeCode
s 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.
