Class Aspect<A>

Object

com.toolsverse.util.aspect.Aspect<A>

Type Parameters:

A - the generic type

All Implemented Interfaces:

javassist.util.proxy.MethodHandler

public abstract class Aspect<A>
extends Object
implements javassist.util.proxy.MethodHandler

Abstract class which implements MethodInterceptor interface. Given the generic type A as a parameter or instance of the Class the Aspect instantiate a new class which extends A but has all methods of the original class intercepted. So it is possible to write a pre or post conditions or completely replace method's code.

The particular class which extends Aspect should override intercept. The default implementation just calls a method from the A class.

Since:

2.0
