Inherited from Protocol:
| Method | logPrefix | Return a prefix matching the class name, to identify log messages related to this protocol instance. |
Inherited from BaseProtocol (via Protocol):
| Method | makeConnection | Make a connection to a transport and a server. |
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.
Clear any circular references here, and any external references to this Protocol. The connection has been closed.
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.
| Parameters | streaming | True if producer provides IPushProducer,
False if producer provides IPullProducer. (type: bool) |
| Returns | None | |
| Raises | RuntimeError | If a producer is already registered. |
The implementation must be non-blocking and perform whatever buffering
is necessary. If the producer has provided enough data for now and it is a
IPushProducer,
the consumer may call its pauseProducing method.
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. |
