void start(ClassPool pool) throws NotFoundException, CannotCompileException
Loader for initialization

This method can be used for getting (for caching) some
CtClass objects that will be accessed
in onLoad() in Translator.pool - the ClassPool that this translator
should use.NotFoundException - if a CtClass cannot be found.CannotCompileException - if the initialization by this method
fails.Loadervoid onLoad(ClassPool pool, String classname) throws NotFoundException, CannotCompileException
Loader for notifying that
a class is loaded. The Loader calls
pool.get(classname).toBytecode()to read the class file after
onLoad() returns.
classname may be the name of a class

If so, onLoad() must create that class so that
the Loader can read it after onLoad()
returns.
