onCompleted	back to summary
public void onCompleted() Implements rx.Observer.onCompleted. Doc from rx.Observer.onCompleted. Notifies the Observer that the `Observable` has finished sending push-based notifications. The `Observable` will not call this method if it calls `onError`. Annotations @Override

public void onCompleted()

Implements rx.Observer.onCompleted.

Doc from rx.Observer.onCompleted.

Notifies the Observer that the Observable has finished sending push-based notifications.

The Observable will not call this method if it calls onError.

onError back to summary

onError	back to summary
public void onError(Throwable e) Implements rx.Observer.onError. Doc from rx.Observer.onError. Notifies the Observer that the `Observable` has experienced an error condition. If the `Observable` calls this method, it will not thereafter call `onNext` or `onCompleted`. Parameters e:Throwable the exception encountered by the Observable Annotations @Override

public void onError(Throwable e)

Implements rx.Observer.onError.

Doc from rx.Observer.onError.

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this method, it will not thereafter call onNext or onCompleted.

Parameters

e:Throwable: the exception encountered by the Observable

onNext	back to summary
public void onNext(R t) Implements rx.Observer.onNext. Doc from rx.Observer.onNext. Provides the Observer with a new item to observe. The `Observable` may call this method 0 or more times. The `Observable` will not call this method again after it calls either `onCompleted` or `onError`. Parameters t:R the item emitted by the Observable Annotations @Override

public void onNext(R t)

Implements rx.Observer.onNext.

Doc from rx.Observer.onNext.

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either onCompleted or onError.

Parameters

t:R: the item emitted by the Observable

request back to summary

request	back to summary
public void request(long n) Implements rx.Producer.request. Doc from rx.Producer.request. Request a certain maximum number of items from this Producer. This is a way of requesting backpressure. To disable backpressure, pass `Long.MAX_VALUE` to this method. Requests are additive but if a sequence of requests totals more than `Long.MAX_VALUE` then `Long.MAX_VALUE` requests will be actioned and the extras may be ignored. Arriving at `Long.MAX_VALUE` by addition of requests cannot be assumed to disable backpressure. For example, the code below may result in `Long.MAX_VALUE` requests being actioned only. request(100); request(Long.MAX_VALUE-1); Parameters n:long the maximum number of items you want this Producer to produce, or `Long.MAX_VALUE` if you want the Producer to produce items at its own pace Annotations @Override

public void request(long n)

Implements rx.Producer.request.

Doc from rx.Producer.request.

Request a certain maximum number of items from this Producer. This is a way of requesting backpressure. To disable backpressure, pass Long.MAX_VALUE to this method.

Requests are additive but if a sequence of requests totals more than Long.MAX_VALUE then Long.MAX_VALUE requests will be actioned and the extras may be ignored. Arriving at Long.MAX_VALUE by addition of requests cannot be assumed to disable backpressure. For example, the code below may result in Long.MAX_VALUE requests being actioned only.

request(100);
request(Long.MAX_VALUE-1);

Parameters

n:long: the maximum number of items you want this Producer to produce, or Long.MAX_VALUE if you want the Producer to produce items at its own pace
