ProcessReader

I am a selectable representation of a process's output pipe, such as stdout and stderr.

Method __init__ Initialize, specifying a process to connect to.
Method fileno Return the fileno() of my process's stderr.
Method writeSomeData Write as much as possible of the given data, immediately.
Method doRead This is called when the pipe becomes readable.
Method dataReceived Undocumented
Method loseConnection Close the connection at the next available opportunity.
Method connectionLost Close my end of the pipe, signal the Process (which signals the ProcessProtocol).

Inherited from _LogOwner (via FileDescriptor):

Method logPrefix Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines.
Method _getLogPrefix Determine the log prefix to use for messages related to applicationObject, which may or may not be an interfaces.ILoggingContext provider.

def __init__(self, reactor, proc, name, fileno): (source)

Initialize, specifying a process to connect to.

def fileno(self): (source)

Return the fileno() of my process's stderr.

def writeSomeData(self, data): (source)

Write as much as possible of the given data, immediately.

This is called to invoke the lower-level writing functionality, such as a socket's send() method, or a file's write(); this method returns an integer or an exception. If an integer, it is the number of bytes written (possibly zero); if an exception, it indicates the connection was lost.

def doRead(self): (source)

This is called when the pipe becomes readable.

def dataReceived(self, data): (source)
Undocumented
def loseConnection(self): (source)

Close the connection at the next available opportunity.

Call this to cause this FileDescriptor to lose its connection. It will first write any data that it has buffered.

If there is data buffered yet to be written, this method will cause the transport to lose its connection as soon as it's done flushing its write buffer. If you have a producer registered, the connection won't be closed until the producer is finished. Therefore, make sure you unregister your producer when it's finished, or the connection will never close.

def connectionLost(self, reason): (source)

Close my end of the pipe, signal the Process (which signals the ProcessProtocol).
