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 FileDescriptor:

Method logPrefix Returns the default log prefix
Method doWrite Called when data can be written.
Method writeConnectionLost Indicates write connection was lost.
Method readConnectionLost Indicates read connection was lost.
Method write Reliably write some data.
Method writeSequence Reliably write a sequence of data.
Method loseWriteConnection Undocumented
Method stopReading Stop waiting for read availability.
Method stopWriting Stop waiting for write availability.
Method startReading Start waiting for read availability.
Method startWriting Start waiting for write availability.
Method stopConsuming Stop consuming data.
Method resumeProducing Undocumented
Method pauseProducing Undocumented
Method stopProducing Stop producing data.
Method _postLoseConnection Called after a loseConnection(), when all data has been written.
Method _closeWriteConnection Undocumented

Inherited from _ConsumerMixin (via FileDescriptor):

Method registerProducer Register to receive data from a producer.
Method unregisterProducer Stop consuming data from a producer, without disconnecting.
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).
