Package org.apache.storm.hooks

Class ITaskHookDelegate

java.lang.Object

org.apache.storm.hooks.ITaskHookDelegate

All Implemented Interfaces:

org.apache.heron.api.hooks.ITaskHook

public class ITaskHookDelegate
extends Object
implements org.apache.heron.api.hooks.ITaskHook

There would be types of task hooks inside ITaskHookDelegate: 1. task hook's classes specified in config statically. The task hooks' objects would be instantiated by using reflection and added into the list of ITaskHook when the method prepare(Map conf, org.apache.heron.api.topology.TopologyContext context) is invoked. 2. task hook added dynamically by invoking addHook(ITaskHook)
