Stop producing data.
This tells a producer that its consumer has died, so it must stop producing data for good.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.
IPushProducer
providers, pauseProducing will be called whenever the write
buffer fills up and resumeProducing will only be called when
it empties.
| Parameters | producer | (type: IProducer
