package com.jredu.schooltong.manager;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ExecutorManager {
// 1.私有构造函数，提供静态变量用以存储，提供静态的方法
private ExecutorManager() {
init();

}

// 静态变量
private static ExecutorManager instance;

// 静态方法
public static ExecutorManager getInstance() {

if (instance == null) {
//加锁
synchronized (ExecutorManager.class) {
if (instance == null) {
instance = new ExecutorManager();
}
}
}
return instance;
}

// 运用单例模式，保证只能够被实例化一次
// 这个类就能应用到其他APP中了
private ExecutorService executorService;

// 初始化线程池
private void init() {
int threadCount = Runtime.getRuntime().availableProcessors() * 2 + 1;
executorService = Executors
.newFixedThreadPool(Math.min(threadCount, 8));

}
public ExecutorService getExecutor(){
return this.executorService;
}
public void execute(Runnable runnable){
this.executorService.execute(runnable);
}
