Member Function Documentation

bool Datacratic::PeriodicEventSource::processOne

(

)

[virtual]

Process a single message and return true if there are more to be processed.

This may be called from more than one thread if singleThreaded() is false.

Implements Datacratic::AsyncEventSource.

Definition at line 120 of file async_event_source.cc.

int Datacratic::PeriodicEventSource::selectFd

(

)

const [virtual]

Return the file descriptor on which one should select() for messages from this source. The source should organize itself such that if the fd indicates ready for a read, there is something to do.

Should return -1 if it requires polling.

Should never block.

Reimplemented from Datacratic::AsyncEventSource.

Definition at line 113 of file async_event_source.cc.

virtual bool Datacratic::PeriodicEventSource::singleThreaded

(

)

const [inline, virtual]

Return whether the callbacks need to be called from a single thread or not.

Reimplemented from Datacratic::AsyncEventSource.

Definition at line 134 of file async_event_source.h.
