类 ExecutionService

java.lang.Object

java.util.concurrent.AbstractExecutorService

com.fr.third.jgroups.blocks.executor.ExecutionService

所有已实现的接口:

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

public class ExecutionService
extends java.util.concurrent.AbstractExecutorService

This is a jgroups implementation of an ExecutorService, where the consumers are running on any number of nodes. The nodes should run ExecutionRunner to start picking up requests.

Every future object returned will be a NotifyingFuture which allows for not having to query the future and have a callback instead. This can then be used as a workflow to submit other tasks sequentially or also to query the future for the value at that time.

Every callable or runnable submitted must be either Serializable or Streamable. Also the value returned from a callable must Serializable or Streamable. Unfortunately if the value returned is not serializable then a NotSerializableException will be thrown as the cause.

从以下版本开始:

2.12.0

嵌套类概要

嵌套类

限定符和类型	类和说明
static class	ExecutionService.DistributedFuture<V> This is basically a copy of the FutureTask in java.util.concurrent but added serializable to it.
protected static class	ExecutionService.RunnableAdapter<T> This is copied from Executors class which contains RunnableAdapter.
