View In Hierarchy

This class provides a simple interface to wake up the event loop.

This is used by threads or signals to wake up the event loop.

Method | `wakeUp` | Write one byte to the pipe, and flush it.

Inherited from `_FDWaker`:

Method | `__init__` | Initialize.
Method | `connectionLost` | Close both ends of my pipe.
Method | `doRead` | Read some bytes from the pipe and discard them.
Class Variable | `disconnected` | Undocumented
Instance Variable | `fileno` | No summary
Instance Variable | `i` | The file descriptor which should be monitored in order to be awoken by this waker.
Instance Variable | `o` | The file descriptor for the end of the pipe which can be written to wake up a reactor monitoring this waker.

Inherited from `Logger` (via `_FDWaker`):

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.
