Public Member Functions | |
| virtual bool | prepare (const State &state, int64 *timeout_usecs_p)=0 |
| Prepare the source for dispatching (true return) or polling (false). | |
| virtual bool | check (const State &state)=0 |
| Check the source and its PollFD descriptors for dispatching (true return). | |
| virtual bool | dispatch (const State &state)=0 |
| Dispatch source, returns if it should be kept alive. | |
| virtual void | destroy () |
| bool | recursion () const |
| Indicates wether the source is currently in recursion. | |
| bool | may_recurse () const |
| Indicates if this source may recurse. | |
| void | may_recurse (bool may_recurse) |
| Dispatch this source if its running recursively. | |
| bool | primary () const |
| Indicate whether this source is primary. | |
| void | primary (bool is_primary) |
| Set whether this source prevents its loop from exiting. | |
| void | add_poll (PollFD *const pfd) |
| Add a PollFD descriptors for poll(2) and check(). | |
| void | remove_poll (PollFD *const pfd) |
| Remove a previously added PollFD. | |
| void | loop_remove () |
| Remove this source from its event loop if any. | |
| MainLoop * | main_loop () const |
