Class Mixin

java.lang.Object
  org.codehaus.nanning.Mixin

All Implemented Interfaces:

java.io.Serializable

public class Mixin

extends java.lang.Object

implements java.io.Serializable

A mixin consists of an interface, a target and a number of interceptors intercepting calls to methods, a mixin can also be a concrete class (no interface/implementation-separation) but at most one mixins with conrete classes per AspectInstance is supported. Create a mixin with interface and target:

new MixinInstance(Interface.class, new Target());

Create a mixin with a concrete class:

new MixinInstance(Target.class);

Add interceptor to method:

Method method = Target.class.getMethod("method", null);
MixinInstance mixin = new MixinInstance(Target.class);
mixin.addInterceptor(method, new MethodInterceptor() {
    public Object invoke(Invocation invocation) {
        return invocation.invokeNext();
    }
}
