Interface CallbackFilter

All Known Implementing Classes:

CallbackHelper

public interface CallbackFilter

Map methods of subclasses generated by Enhancer 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 keep CallbackFilter objects alive to enable caching of generated classes. Prefer using static classes for implementation of CallbackFilter.

Method Summary

Modifier and Type	Method	Description
int	accept(Method method)	Map a method to a callback.
boolean	equals(Object o)	The CallbackFilter in use affects which cached class the Enhancer will use, so this is a reminder that you should correctly implement equals and hashCode for custom CallbackFilter implementations in order to improve performance.

Method Details

accept

int accept(Method method)

Map a method to a callback.

Parameters:

method - the intercepted method

Returns:

the index into the array of callbacks (as specified by Enhancer.setCallbacks(org.springframework.cglib.proxy.Callback[])) to use for the method,

equals

boolean equals(Object o)

The CallbackFilter in use affects which cached class the Enhancer will use, so this is a reminder that you should correctly implement equals and hashCode for custom CallbackFilter implementations in order to improve performance.

Overrides:

equals in class Object
