virtual void caf::io::network::event_handler::handle_event ( operation  op)
pure virtual

Returns true once the requested operation is done, i.e., to signalize the multiplexer to remove this handler.

The handler remains in the event loop as long as it returns false.

Implemented in caf::io::network::acceptor, caf::io::network::stream, and caf::io::network::pipe_reader.

virtual void caf::io::network::event_handler::removed_from_loop ( operation  op)
pure virtual

Callback to signalize that this handler has been removed from the event loop for operations of type op.

Implemented in caf::io::network::acceptor, caf::io::network::stream, and caf::io::network::pipe_reader.
