|Method||connectionMade||Called when a connection is made.|
|Method||connectionLost||Called when the connection is shut down.|
|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.|
|Method||dataReceived||Called whenever data is received.|
|Method||makeConnection||Make a connection to a transport and a server.|
Called when a connection is made.This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here.
Called when the connection is shut down.Clear any circular references here, and any external references to this Protocol. The connection has been closed.
|Parameters||reason|| (type: |
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().
resumeProducing will be called once each time data
pauseProducingwill be called whenever the write buffer fills up and
resumeProducingwill only be called when it empties.
|Parameters||producer|| (type: |
Called whenever data is received.Use this method to translate to a higher-level message. Usually, some callback will be made upon the receipt of each complete protocol message.
|Parameters||data||a string of indeterminate length. Please keep in mind that you will probably need to buffer some data, as partial (or multiple) protocol messages may be received! I recommend that unit tests for protocols call through to this method with differing chunk sizes, down to one byte at a time.|
