Interface CallbackFilter
-
- All Known Implementing Classes:
CallbackHelper
public interface CallbackFilter
Map methods of subclasses generated byEnhancer
to a particular callback. The type of the callbacks chosen for each method affects the bytecode generated for that method in the subclass, and cannot change for the life of the class.Note:
CallbackFilter
implementations are supposed to be lightweight as cglib might keepCallbackFilter
objects alive to enable caching of generated classes. Prefer usingstatic
classes for implementation ofCallbackFilter
.

Method Summary
All Methods Instance Methods Abstract Methods Modifier and Type Method Description int
accept(java.lang.reflect.Method method)
Map a method to a callback.boolean
equals(java.lang.Object o)
TheCallbackFilter
in use affects which cached class theEnhancer
will use, so this is a reminder that you should correctly implementequals
andhashCode
for customCallbackFilter
implementations in order to improve performance.

accept
int accept(java.lang.reflect.Method method)
Map a method to a callback.- Parameters:
