Class TreeClassAdapter

java.lang.Object
  org.logicalcobwebs.asm.ClassAdapter
      org.logicalcobwebs.asm.tree.TreeClassAdapter

All Implemented Interfaces:

ClassVisitor

public class TreeClassAdapter

extends ClassAdapter

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);
 }

Method Detail

visit

public void visit(int access,
                  java.lang.String name,
                  java.lang.String superName,
                  java.lang.String[] interfaces,
                  java.lang.String sourceFile)

Description copied from interface: ClassVisitor

Visits the header of the class.

Specified by:

visit in interface ClassVisitor

Overrides:

visit in class ClassAdapter

visitInnerClass

public void visitInnerClass(java.lang.String name,
                            java.lang.String outerName,
                            java.lang.String innerName,
                            int access)

Description copied from interface: ClassVisitor

Visits information about an inner class. This inner class is not necessarily a member of the class being visited.

Specified by:

visitInnerClass in interface ClassVisitor

Overrides:

visitInnerClass in class ClassAdapter

visitField

public void visitField(int access,
                       java.lang.String name,
                       java.lang.String desc,
                       java.lang.Object value,
                       Attribute attrs)

Description copied from interface: ClassVisitor

Visits a field of the class.

Specified by:

visitField in interface ClassVisitor

Overrides:

visitField in class ClassAdapter

visitMethod

public CodeVisitor visitMethod(int access,
                               java.lang.String name,
                               java.lang.String desc,

                               Attribute attrs)

Description copied from interface: ClassVisitor

Visits a method of the class. This method must return a new CodeVisitor instance (or null) each time it is called, i.e., it should not return a previously returned visitor.

Specified by:

visitMethod in interface ClassVisitor

Overrides:

visitMethod in class ClassAdapter

Specified by:

visitAttribute in interface ClassVisitor

Overrides:

visitAttribute in class ClassAdapter

visitEnd

Description copied from interface: ClassVisitor

Visits the end of the class. This method, which is the last one to be called, is used to inform the visitor that all the fields and methods of the class have been visited.

Specified by:

visitEnd in interface ClassVisitor

Overrides:
