public final Class ExceptionTable

extends Attribute
Class Inheritance
Imports
java.io.DataInputStream, .DataOutputStream, .IOException, org.aspectj.apache.bcel.Constants
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).
