Derived classes
- class DispatcherSource virtual
- EventLoop source for handler execution.
- class PollFDSource virtual
- EventLoop source for IO callbacks.
- class TimedSource virtual
- EventLoop source for timer execution.
- class USignalSource virtual

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