Deliver the event to all registered listeners MSX input devices should call the distributeNew() version, only the replayer should call the distributeReplay() version.

These two different versions are used to detect the transition from replayed events to live events. Note that a transition from live to replay is not allowed. This transition should be done by creating a new StateChangeDistributor object (object always starts in replay state), but this is automatically taken care of because replay always starts from a freshly restored snapshot. Instead of a 'StateChange' parameter this method takes a template-parameter 'T' and run-time parameters 'time' and '...arg' that together can construct a 'StateChange' subclass 'T'.

◆ registerListener()

void openmsx::StateChangeDistributor::registerListener ( StateChangeListener & listener )

(Un)registers the given object to receive state change events.

Parameters

listener Listener that will be notified when an event arrives.

◆ registerRecorder()

void openmsx::StateChangeDistributor::registerRecorder ( ReverseManager & recorder )

(Un)registers the given object to receive state change events.

Parameters

recorder Listener that will be notified when an event arrives. These two methods are very similar to the two above. The difference is that there can be at most one registered recorder. This recorder object is always the first object that gets informed about state changing events.

◆ setViewOnlyMode()

void openmsx::StateChangeDistributor::setViewOnlyMode ( bool value )

inline

Set viewOnlyMode.

Call this if you don't want distributeNew events to stop replaying and go to live events (value=true).

Parameters

value false if new events stop replay mode

Definition at line 81 of file StateChangeDistributor.hh.

◆ stopReplay()

void openmsx::StateChangeDistributor::stopReplay ( EmuTime::param time )

Explicitly stop replay.

Should be called when replay->live transition cannot be signaled via a new event, so for example when we reach the end of the replay log. It's OK to call this method when replay was already stopped, in that case this call has no effect.
