Examples of javassist.CtConstructor

javassist.CtConstructor
An instance of CtConstructor represents a constructor. It may represent a static constructor (class initializer). To distinguish a constructor and a class initializer, call isClassInitializer().
See the super class CtBehavior as well since a number of useful methods are in CtBehavior. @see CtClass#getDeclaredConstructors() @see CtClass#getClassInitializer() @see CtNewConstructor
