t.t.p.AccumulatingProtocol(protocol.Protocol) : class documentation

Part of twisted.test.proto_helpers View Source View In Hierarchy

AccumulatingProtocol is an IProtocol implementation which collects the data delivered to it and can fire a Deferred when it is connected or disconnected.

Instance Variable made A flag indicating whether connectionMade has been called.
Instance Variable data Bytes giving all the data passed to dataReceived.
Instance Variable closed A flag indicated whether connectionLost has been called.
Instance Variable closedReason The value of the reason parameter passed to connectionLost.
Instance Variable closedDeferred If set to a Deferred, this will be fired when connectionLost is called.
Method connectionMade Called when a connection is made.
Method dataReceived Called whenever data is received.
Method connectionLost Called when the connection is shut down.

Inherited from BaseProtocol (via Protocol):

Method makeConnection Make a connection to a transport and a server.

made =

closedReason =
The value of the reason parameter passed to connectionLost.
closedDeferred =
If set to a Deferred, this will be fired when connectionLost is called.
def connectionMade(self): (source)

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.

def dataReceived(self, data): (source)

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.

Parametersdataa 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.
def connectionLost(self, reason): (source)

Called when the connection is shut down.

Clear any circular references here, and any external references to this Protocol. The connection has been closed.
