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. |
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.
