Class ExtensibleExecutorService

java.lang.Object

java.util.concurrent.AbstractExecutorService

org.apache.river.thread.ExtensibleExecutorService

All Implemented Interfaces:

java.util.concurrent.Executor, java.util.concurrent.ExecutorService

public class ExtensibleExecutorService
extends java.util.concurrent.AbstractExecutorService

AbstractExecutorService introduced two protected methods in Java 1.6 to allow an ExecutorService to use customised RunnableFuture implementations other than the default FutureTask. This class requires a Factory to create the RunnableFuture, encapsulating any existing ExecutorService. This allows an ExecutorService to be provided by Configuration or a pool to be shared without requiring that all implementations also share the same type of RunnableFuture.
