oracle.toplink.libraries.asm.ClassAdapter
oracle.toplink.libraries.asm.tree.TreeClassAdapter
public class TreeClassAdapter
A ClassAdapter
that constructs a tree representation of the classes it vists. Each visitXXX method of this class constructs an XXXNode and adds it to the classNode
node (except the visitEnd
method, which just makes the cv
class visitor visit the tree that has just been constructed).
In order to implement a usefull class adapter based on a tree representation of classes, one just need to override the visitEnd
method with a method of the following form:
public void visitEnd () { // ... // code to modify the classNode tree, can be arbitrary complex // ... // makes the cv visitor visit this modified class: classNode.accept(cv); }
