class twisted.internet.process.ProcessReader(abstract.FileDescriptor): (source)
ProcessReader
I am a selectable representation of a process's output pipe, such as stdout and stderr.
| Class Variable | connected | Undocumented |
| Method | __init__ | Initialize, specifying a process to connect to. |
| Instance Variable | proc | Undocumented |
| Instance Variable | name | Undocumented |
| Instance Variable | fd | Undocumented |
| 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. |
| Instance Variable | disconnecting | Undocumented |
| Method | connectionLost | Close my end of the pipe, signal the Process (which signals the ProcessProtocol). |
Inherited from FileDescriptor:
| Instance Variable | disconnected | Undocumented |
| Instance Variable | dataBuffer | Undocumented |
| Instance Variable | offset | Undocumented |
| Class Variable | SEND_LIMIT | Undocumented |
| Instance Variable | reactor | Undocumented |
| Instance Variable | producer | Undocumented |
| Method | doWrite | Called when data can be written. |
| Instance Variable | producerPaused | Undocumented |
| Method | writeConnectionLost | Undocumented |
| Method | readConnectionLost | Undocumented |
| Method | getHost | Undocumented |
| Method | getPeer | Undocumented |
| 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. |
| Class Variable | bufferSize | Undocumented |
| Method | stopConsuming | Stop consuming data. |
| Method | resumeProducing | Undocumented |
| Method | pauseProducing | Undocumented |
| Method | stopProducing | Undocumented |
| Instance Variable | _writeDisconnecting | Undocumented |
| Instance Variable | _writeDisconnected | Undocumented |
| Instance Variable | _tempDataBuffer | Undocumented |
| Instance Variable | _tempDataLen | Undocumented |
| Method | _postLoseConnection | Called after a loseConnection(), when all data has been written. |
| Method | _closeWriteConnection | Undocumented |
| Method | _isSendBufferFull | Determine whether the user-space send buffer for this transport is full or not. |
| Method | _maybePauseProducer | Possibly pause a producer, if there is one and the send buffer is full. |
Inherited from _ConsumerMixin (via FileDescriptor):
| Instance Variable | streamingProducer | bool or int |
| Method | registerProducer | Register to receive data from a producer. |
| Method | unregisterProducer | Stop consuming data from a producer, without disconnecting. |
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. |
Initialize, specifying a process to connect to.
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.
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.
Close my end of the pipe, signal the Process (which signals the ProcessProtocol).
