Examples of org.apache.bcel.classfile.Attribute

org.apache.bcel.classfile.Attribute
Abstract super class for Attribute objects. Currently the ConstantValue, SourceFile, Code, Exceptiontable, LineNumberTable, LocalVariableTable, InnerClasses and Synthetic attributes are supported. The Unknown attribute stands for non-standard-attributes. @version $Id: Attribute.java,v 1.2 2001/11/20 11:41:05 mdahm Exp $ @author M.
