t.i.u._BackRelay(protocol.ProcessProtocol) : class documentation

Trivial protocol for communicating with a process and turning its output into the result of a Deferred.

Instance Variables	deferred	A Deferred which will be called back with all of stdout and, if errortoo is true, all of stderr as well (mixed together in one string). If errortoo is false and any bytes are received over stderr, this will fire with an _UnexpectedErrorOutput instance and the attribute will be set to None.
	onProcessEnded	If errortoo is false and bytes are received over stderr, this attribute will refer to a Deferred which will be called back when the process ends. This Deferred is also associated with the _UnexpectedErrorOutput which deferred fires with earlier in this case so that users can determine when the process has actually ended, in addition to knowing when bytes have been received via stderr.

Method	__init__	Undocumented
Method	errReceivedIsBad	Undocumented
Method	errReceivedIsGood	Undocumented
Method	outReceived	Some data was received from stdout.
Method	processEnded	This will be called when the subprocess is finished.

Inherited from ProcessProtocol:

Method	childDataReceived	Called when data arrives from the child process.
Method	errReceived	Some data was received from stderr.
Method	childConnectionLost	Called when a file descriptor associated with the child process is closed.
Method	inConnectionLost	This will be called when stdin is closed.
Method	outConnectionLost	This will be called when stdout is closed.
Method	errConnectionLost	This will be called when stderr is closed.
Method	processExited	This will be called when the subprocess exits.

Inherited from BaseProtocol (via ProcessProtocol):

Method	makeConnection	Make a connection to a transport and a server.
Method	connectionMade	Called when a connection is made.
