transform

public boolean transform(javassist.CtClass clazz,
                         ClassAdvisor classAdvisor)
                  throws Exception

Transforms the constructor executions of this class according to the pointcuts registered in AspectManager.

Parameters:

clazz - the clazz to be transformed.

classAdvisor - the advisor associated to clazz.

Returns:

true is clazz is instrumented.

Throws:

Exception

wrap

public void wrap(javassist.CtClass clazz,
                 Collection constructorIndexes)
          throws Exception

Wraps the constructor executions contained in constructorIndexes.

Parameters:

clazz - the class being instrumented.

constructorIndexes - a collection of java.lang.Integer indentifying the constructors to be wrapped.

Throws:

Exception

unwrap

public void unwrap(javassist.CtClass clazz,
                   Collection constructorIndexes)
            throws javassist.NotFoundException

Unwraps the constructor executions contained in constructorIndexes.

Parameters:

clazz - the class being instrumented.

constructorIndexes - a collection of java.lang.Integer indentifying the constructors to be unwrapped.

Throws:

javassist.NotFoundException

codeConverted
