RxJava CompositeDisposable类

RxJava Observable CompositeDisposable类 介绍

CompositeDisposable 类表示一个容器，它可以容纳多个一次性物品，并提供 O(1) 添加和删除一次性物品的复杂性。

RxJava Observable CompositeDisposable类 声明

public final class CompositeDisposable
extends Object
implements Disposable, io.reactivex.internal.disposables.DisposableContainer

RxJava Observable CompositeDisposable类 协议

以下是 Single Observable 操作的顺序协议：

onSubscribe (onSuccess | onError)?

RxJava Observable CompositeDisposable类 示例

package cn.xnip;

import io.reactivex.Maybe;
import io.reactivex.Single;
import io.reactivex.disposables.CompositeDisposable;
import io.reactivex.disposables.Disposable;
import io.reactivex.observers.DisposableMaybeObserver;
import io.reactivex.observers.DisposableSingleObserver;
import io.reactivex.schedulers.Schedulers;

import java.util.concurrent.TimeUnit;

public class ObservableTester  {
   public static void main(String[] args)  throws InterruptedException {    
      CompositeDisposable compositeDisposable = new CompositeDisposable();

      //Create an Single observer 
      Disposable disposableSingle = Single.just("小牛知识库网")
      .delay(2, TimeUnit.SECONDS, Schedulers.io())
      .subscribeWith(
      new DisposableSingleObserver<String>() {
         @Override
         public void onError(Throwable e) {
            e.printStackTrace();
         }

         @Override
         public void onSuccess(String value) {
            System.out.println(value);
         }
      }); 

      //Create an observer
      Disposable disposableMayBe = Maybe.just("你好")
      .delay(2, TimeUnit.SECONDS, Schedulers.io())
      .subscribeWith(new DisposableMaybeObserver<String>() {
         @Override
         public void onError(Throwable e) { 
            e.printStackTrace();
         }

         @Override
         public void onSuccess(String value) {
            System.out.println(value);
         }

         @Override
         public void onComplete() {
            System.out.println("Done!");
         }
      }); 

      Thread.sleep(3000);

      compositeDisposable.add(disposableSingle);
      compositeDisposable.add(disposableMayBe);

      //start observing
      compositeDisposable.dispose();
   }
}

输出结果为：
