More hypothetical (memory would probably be doomed anyway) check whether there would be an overflow when adding an area, setting the proper state if so.

Returns: HardRecalcState::ETERNAL if a HardRecalcState is effective and area is not to be added.

bool ScBroadcastAreaSlot::StartListeningArea	(	const ScRange &	rRange,
		bool	bGroupListening,
		SvtListener *	pListener,
		ScBroadcastArea *&	rpArea
	)

Only here new ScBroadcastArea objects are created, prevention of dupes.

Parameters

rpArea If NULL, a new ScBroadcastArea is created and assigned ton the reference if a matching area wasn't found. If a matching area was found, that is assigned. In any case, the SvtListener is added to the broadcaster.

If not NULL then no listeners are started, only the area is inserted and the reference count incremented. Effectively the same as InsertListeningArea(), so use that instead.

Returns: true if rpArea passed was NULL and ScBroadcastArea is newly created.

bool ScBroadcastAreaSlot::mbHasErasedArea

private

If true, the slot has at least one area broadcaster marked for removal.

This flag is used only during broadcast iteration, to speed up iteration. Using this flag is cheaper than dereferencing each iterator and checking its own flag inside especially when no areas are marked for removal.
