Method Detail

edit

public javassist.CtClass edit(java.lang.String cName)
                       throws javassist.NotFoundException,
                              javassist.CannotCompileException

Description copied from class: BasicInstrumentor

Provides a hook to instrument a class specified by name. The default implementation excludes instrumenting classes that are excluded implicitly or explicitly; for each class that is not excluded, it calls the BasicInstrumentor.edit(CtClass) method.

Overrides:

edit in class BasicInstrumentor

Parameters:

cName - Name of the class to be instrumented (e.g., java.lang.Object).

Returns:

The instrumented class in Javassist's representation. It must be null if the class is not instrumented.

Throws:

javassist.NotFoundException - If Javassist fails to find the class.

javassist.CannotCompileException - If Javassist fails to correctly instrument the class.

edit

public javassist.CtClass edit(javassist.CtClass clazz)
                       throws javassist.CannotCompileException

Description copied from class: BasicInstrumentor

Provides a hook to instrument a class specified in Javassist's representation. The default implementation calls the hooks to instrument all its methods, including its class initializer method (if any), all its declared constructors, and all its declared methods.

Overrides:

edit in class BasicInstrumentor

Parameters:

clazz - Javassist's representation of the class to be instrumented.

Returns:

The instrumented class in Javassist's representation. It must be null if the class is not instrumented.

Throws:

javassist.CannotCompileException - If Javassist fails to correctly instrument the class.
