com.vladium.jcd.cls

类 ClassDef

java.lang.Object

com.vladium.jcd.cls.ClassDef

所有已实现的接口:

IAccessFlags, IClassFormatOutput, java.lang.Cloneable

public final class ClassDef
extends java.lang.Object
implements java.lang.Cloneable, IAccessFlags, IClassFormatOutput

This class represents the abstract syntax table (AST) that ClassDefParser produces from bytecode. Most elements are either settable or extendible. This class also implements IClassFormatOutput and works with ClassWriter to produce bytecode without an external compiler.

MT-safety: this class and all interfaces used by it are not safe for access from multiple concurrent threads.
