Method Details

initialize

public void initialize(ConstPool cp,
 CodeAttribute attr)

Overrides:

initialize in class Transformer

transform

public int transform(CtClass clazz,
 int pos,
 CodeIterator iterator,
 ConstPool cp)
              throws BadBytecode

Modify INVOKEINTERFACE, INVOKESPECIAL, INVOKESTATIC and INVOKEVIRTUAL so that a different method is invoked. The class name in the operand of these instructions might be a subclass of the target class specified by classname. This method transforms the instruction in that case unless the subclass overrides the target method.

Specified by:

transform in class Transformer

Throws:

BadBytecode

private boolean matchClass(String name,
 ClassPool pool)

match

protected int match(int c,
 int pos,
 CodeIterator iterator,
 int typedesc,
 ConstPool cp)
             throws BadBytecode

Throws:
