A consumer consumes data from a producer.
Method registerProducer Register to receive data from a producer.
Method unregisterProducer Stop consuming data from a producer, without disconnecting.
Method write The producer will write data by calling this method.
def registerProducer(producer, streaming): (source)

Register to receive data from a producer.

This sets self to be a consumer for a producer. When this object runs out of data (as when a send(2) call on a socket succeeds in moving the last data from a userspace buffer into a kernelspace buffer), it will ask the producer to resumeProducing().

For IPullProducer providers, resumeProducing will be called once each time data is required.

For IPushProducer providers, pauseProducing will be called whenever the write buffer fills up and resumeProducing will only be called when it empties.
Parametersproducer (type: IProducer provider )
streamingTrue if producer provides IPushProducer, False if producer provides IPullProducer. (type: bool )
ReturnsNone
def unregisterProducer(): (source)
Stop consuming data from a producer, without disconnecting.
def write(data): (source)
The producer will write data by calling this method.
