本文整理了Java中io.reactivex.Observable.ignoreElements()方法的一些代码示例，展示了Observable.ignoreElements()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Observable.ignoreElements()方法的具体详情如下：
包路径：io.reactivex.Observable
类名称：Observable
方法名：ignoreElements

Observable.ignoreElements介绍

[英]Ignores all items emitted by the source ObservableSource and only calls onComplete or onError.

Scheduler: ignoreElements does not operate by default on a particular Scheduler.
[中]忽略源ObservableSource发出的所有项，只调用onComplete或onError。
调度器：默认情况下，ignoreElements不会在特定的调度器上运行。

@Override
  public Completable adapt(Call<T> call, AdapterParam param) {
    ObservableResponse<T> observable = new ObservableResponse<>();
    return observable.adapt(call, param).ignoreElements();
  }
}
