Examples of org.apache.bcel.classfile.ExceptionTable

org.apache.bcel.classfile.ExceptionTable
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). @version $Id: ExceptionTable.java 386056 2006-03-15 11:31:56Z tcurdt $ @author M.
