- Selection type, for example aMove
class, an entity class or a value class.

public abstract class UpcomingSelectionIterator<S> extends SelectionIterator<S>
IMPORTANT: The constructor of any subclass of this abstract class, should never call any of its childSelector
'sIterator.hasNext()
orIterator.next()
methods, because that can cause descendantSelector
s to be selected too early (which breaksMimicReplayingEntitySelector
).
