Class InterceptorChain

java.lang.Object

org.jahia.services.content.interceptor.InterceptorChain

public class InterceptorChain
extends Object

Calls all property interceptors in a chain. Interceptors are called one after the other.

Setting a property :

v1 = interceptor1.beforeSet(v) v2 = interceptor2.beforeSet(v1) v3 = interceptor3.beforeSet(v2) .. property set (v3)

Getting a property :

v = get property v1 = interceptor3.afterGet(v) v2 = interceptor2.afterGet(v1) v3 = interceptor1.afterGet(v2) ... return v3
