public class InitializedValueSelector extends AbstractValueSelector
Filters out every value that is a planning entity for which the PlanningVariable
(on which this ValueSelector
applies to) is uninitialized.
Mainly used for chained planning variables, but supports other planning variables too.

isNeverEnding()
Is true if

This returns an ending Iterator

as much as possible,
but return each distinct element only once
and therefore it might not respect the configuration of this ValueSelector
