RxJava - Using CompositeDisposable
CompositeDisposable 类表示一个容器，可以容纳多个可释放对象，并提供 O(1) 的复杂度来添加和删除可释放对象。
Class Declaration
以下是 io.reactivex.disposables.CompositeDisposable 类的声明 −
public final class CompositeDisposable
extends Object
implements Disposable, io.reactivex.internal.disposables.DisposableContainerCompositeDisposable Example
在任意编辑器中使用任何您选择的语言（如 C:\>RxJava) 创建以下 Java 程序。
ObservableTester.java
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("Hello World")
.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("Hi")
.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();
}
}
