Examples of javassist.CtField$PtreeInitializer

javassist.CtField
Instances of this class specify how to initialize a field. Initializer is passed to CtClass.addField() with a CtField.
This class cannot be instantiated with the new operator. Factory methods such as byParameter() and byNew must be used for the instantiation. They create a new instance with the given parameters and return it. @see CtClass#addField(CtField,CtField.Initializer)
