Connects the underling observer to the upstream publisher.
Connects the underling observer to the upstream publisher.
Until this call happens, the underlying observer will not receive
any events. Instead all incoming events are cached. And after
connect the cached events will be fed in the underlying
subscriber and afterwards we connect the underlying subscriber
directly to the upstream source.
This function should be idempotent. Calling it multiple times should have the same effect as calling it once.
The Subscriber.onComplete method that pushes the complete event to the underlying observer.
The Subscriber.onComplete method that pushes the complete event to the underlying observer.
It will wait for connect to happen and the queue of cached events to be drained.
The Subscriber.onError method that pushes an error event to the underlying observer.
The Subscriber.onError method that pushes an error event to the underlying observer.
It will wait for connect to happen and the queue of cached events to be drained.
The Subscriber.onNext method that pushes events to the underlying subscriber.
The Subscriber.onNext method that pushes events to the underlying subscriber.
It will back-pressure by means of its Future[Ack] result
until connect happens and the underlying queue of
cached events have been drained.
Wraps an
underlyingSubscriber into an implementation that caches all events until the call toconnect()happens. After being connected, the buffer is drained into theunderlyingobserver, after which all subsequent events are pushed directly.
