virtual void gr_select_handler::handle_read | ( | ) | [pure virtual] |
Called when file_descriptor is readable.
Called when the dispatcher detects that file_descriptor can be read without blocking.
virtual void gr_select_handler::handle_write | ( | ) | [pure virtual] |
Called when file_descriptor is writable.
Called when dispatcher detects that file descriptor can be written without blocking.
virtual bool gr_select_handler::readable | ( | ) | [inline, virtual] |
Called each time around the dispatcher loop to determine whether this handler's file descriptor should be added to the list on which read events can occur. The default method returns true, indicating that by default, all handlers are interested in read events.
virtual bool gr_select_handler::writable | ( | ) | [inline, virtual] |
Called each time around the dispatcher loop to determine whether this handler's file descriptor should be added to the list on which write events can occur. The default method returns true, indicating that by default, all handlers are interested in write events.
