Method Detail

request

public void request(long n)

Description copied from interface: Producer

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);
 

Specified by:

request in interface Producer

Parameters:

n - 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

isUnsubscribed

public boolean isUnsubscribed()

Description copied from interface: Subscription

Indicates whether this Subscription is currently unsubscribed.

Specified by:

isUnsubscribed in interface Subscription

Returns:

true if this Subscription is currently unsubscribed, false otherwise

unsubscribe

public void unsubscribe()

Description copied from interface: Subscription

Stops the receipt of notifications on the Subscriber that was registered when this Subscription was received.

This allows unregistering an Subscriber before it has finished receiving all events (i.e. before onCompleted is called).

Specified by:

unsubscribe in interface Subscription
