An opaque type passed into playView that may be used by an overriding implementation.
An opaque type passed into playView that may be used by an overriding implementation.
Otherwise it may simply be set to Unit.
Sub-classes may override this and call super.dispose()
if they wish to free additional observers, e.g.

Report the next interesting frame greater than the given frame for which
gridReached (internal) and processPrepare will be called.
Report the next interesting frame greater than the given frame for which
gridReached (internal) and processPrepare will be called.
If no such event exists, the method must return Long.MaxValue.
The view must store a handle to its underlying model.
The view must store a handle to its underlying model.
Ensures state is consistent, then checks preparation of children.
Ensures state is consistent, then checks preparation of children.
If all is good, sets internal state to IPlaying and calls processPlay.
Next instructs scheduler and sets external state to Playing.
Should be called from processPlay.
Should be called from processPlay. It calls play on the view
and adds it to the list of playing views.
Note: timeRef must already have been updated through
appropriate intersection.
Sub-classes may override this if they call super.playView
Note: the prepare span will always start from current-frame and have
a duration of at least LOOK_STOP.
Note: the prepare span will always start from current-frame and have
a duration of at least LOOK_STOP. I.e. during playback it contains the current play position.
Called when a next interesting frame has been reached.
Called when a next interesting frame has been reached. The method should look for and invoke the events such as starting or stopping a view.
Called during play.
Called during play. Sub-classes should intersect
the current elements and for each of them call playView.
Called during preparation of armed elements.
Called during preparation of armed elements. This
happens either during initial prepare or during grid-events.
Given the prepareSpan, the sub-class should
- find the elements using an intersect
- for each build a view and store it somewhere
- for each view call prepareChild
- accumulate the results of prepareChild into a Map that is returned.
The map will become part of IPreparing. (NOT: The returned Boolean indicates
if elements were found (true) or not (false)).
if true this is an initial preparation which means the method
must include views that start before prepareSpan if their span
overlaps with prepareSpan. If false this is a follow up from
gridReached and the search must be restricted to views that
start no earlier than prepareSpan.
Should be called from processEvent for views that should be
stopped and disposed.
Should be called from processEvent for views that should be
stopped and disposed. The caller is responsible for removing
the view also from a view-tree if such structure is maintained.
NOT: This method ends by calling viewRemoved.
Stops and disposes all currently playing views.
Stops and disposes all currently playing views.

eventReached (internal) and processEvent will be called.
Report the next interesting frame greater than the given frame for which
eventReached (internal) and processEvent will be called.
If no such event exists, the method must return Long.MaxValue.
