virtual bool	check (const LoopState & state) = 0 Check the source and its PollFD descriptors for dispatching (true return).
virtual void	destroy ()
virtual bool	dispatch (const LoopState & state) = 0 Dispatch source, returns if it should be kept alive.
void	loop_remove () Remove this source from its event loop if any.
MainLoop *	main_loop () const Get the main loop for this source.
bool	may_recurse () const Indicates if this source may recurse.
void	may_recurse (bool may_recurse) Dispatch this source if its running recursively.
virtual bool	prepare (const LoopState & state, int64 * timeout_usecs_p) = 0 Prepare the source for dispatching (true return) or polling (false).
bool	primary () const Indicate whether this source is primary.
void	primary (bool is_primary) Set whether this source prevents its loop from exiting.
bool	recursion () const Indicates wether the source is currently in recursion.
void	remove_poll (PollFD *const pfd) Remove a previously added PollFD .
