View In Hierarchy

A push producer, also known as a streaming producer is expected to produce (write to this consumer) data on a continuous basis, unless it has been paused. A paused push producer will resume producing after its resumeProducing() method is called. For a push producer which is not pauseable, these functions may be noops.

Method	`pauseProducing`	Pause producing data.
Method	`resumeProducing`	Resume producing data.

Inherited from IProducer:

Method stopProducing Stop producing data.

def pauseProducing(): (source) ¶

Pause producing data.

Tells a producer that it has produced too much data to process for the time being, and to stop until resumeProducing() is called.

def resumeProducing(): (source) ¶

Resume producing data.

This tells a producer to re-add itself to the main loop and produce more data for its consumer.
