Class ExceptionList

Contents

  • public abstract class ExceptionList
extends Object
    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

        Parameters:
        index - the index of the TypeCode object desired. This must be an int between 0 and the number of TypeCode objects minus one, inclusive.
        Returns:
        the TypeCode object at the given index
        Throws:
        Bounds - if the index given is greater than or equal to the number of TypeCode objects in this ExceptionList object

      • remove

        public abstract void remove(int index)
                     throws Bounds
