Member Function Documentation

virtual HandlerID SigCX::Dispatcher::add_exception_handler (  const Handler &  h, int  fd )  [pure virtual]

Add exception handler. The handler h is invoked when an exception occurs on fd. Parameters: h  The input handler. fd  File descriptor. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

virtual HandlerID SigCX::Dispatcher::add_input_handler (  const Handler &  h, int  fd )  [pure virtual]

Add input handler. The handler h is invoked when data is ready for reading from fd. Parameters: h  The input handler. fd  File descriptor. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

virtual HandlerID SigCX::Dispatcher::add_output_handler (  const Handler &  h, int  fd )  [pure virtual]

Add output handler. The handler h is invoked when fd is ready for writing. Parameters: h  The input handler. fd  File descriptor. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

virtual HandlerID SigCX::Dispatcher::add_signal_handler (  const Handler &  h, int  sig )  [pure virtual]

Add signal handler. The handler h is invoked when the signal sig is received by the program. Implemented in SigCX::SignalDispatcher.

virtual HandlerID SigCX::Dispatcher::add_timeout_handler (  const Handler &  h, const TimeVal &  tv )  [pure virtual]

Add timeout handler. The handler h is invoked when the time specified by tv has passed. Parameters: h  The input handler. tv  TimeVal timeout. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

HandlerID SigCX::Dispatcher::add_timeout_handler_msec (  const Handler &  h, unsigned long  tmout )  [inline]

Add timeout handler. The handler h is invoked when the time specified by tv has passed. Parameters: h  The input handler. tmout  timeout in milliseconds.

virtual void SigCX::Dispatcher::exit (   )  [pure virtual]

Cause exit of event loop. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

virtual bool SigCX::Dispatcher::idle (   )  const [pure virtual]

Get idle status. Returns: true if the dispatcher is idle. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

virtual void SigCX::Dispatcher::move (  Dispatcher &  d  )  [pure virtual]

Move all callbacks to another dispatcher. Parameters: d  The dispatcher to move the callbacks to. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

virtual void SigCX::Dispatcher::remove (  HandlerID  id  )  [pure virtual]

Remove a handler. Parameters: id  The ID of the handler. Implemented in SigCX::SignalDispatcher, SigCX::StandardDispatcher, and SigCX::GtkDispatcher.

virtual bool SigCX::Dispatcher::run (  bool  infinite = true  )  [pure virtual]

Run the dispatcher. Run the dispatcher event loop, receiving events and calling the registered callbacks. Parameters: infinite  If false, run only one iteration, else run until exit() is called on this dispatcher instance. Returns: true if exit() was called. Implemented in SigCX::StandardDispatcher, and SigCX::GtkDispatcher.
