Class ExceptionTable

  • All Implemented Interfaces:
    Cloneable, Node

    public final class ExceptionTable
    extends Attribute
    This class represents the table of exceptions that are thrown by a method. This attribute may be used once per method. The name of this class is ExceptionTable for historical reasons; The Java Virtual Machine Specification, Second Edition defines this attribute using the name Exceptions (which is inconsistent with the other classes).
