Class UpcomingSelectionIterator<S>

java.lang.Object
org.optaplanner.core.impl.heuristic.selector.common.iterator.SelectionIterator<S>
org.optaplanner.core.impl.heuristic.selector.common.iterator.UpcomingSelectionIterator<S>
Type Parameters:
S - Selection type, for example a Move class, an entity class or a value class.
All Implemented Interfaces:
Iterator<S>
Direct Known Subclasses:
AbstractOriginalChangeIterator, AbstractOriginalSwapIterator, AbstractRandomChangeIterator, AbstractRandomSwapIterator, CartesianProductMoveSelector.OriginalCartesianProductMoveIterator, FilteringEntitySelector.JustInTimeFilteringEntityIterator, FilteringValueSelector.JustInTimeFilteringValueIterator, InitializedValueSelector.JustInTimeInitializedValueIterator, OriginalListChangeIterator, OriginalListSwapIterator, RandomListChangeIterator, RandomListSwapIterator, UpcomingSelectionListIterator
public abstract class UpcomingSelectionIterator<S> extends SelectionIterator<S>
IMPORTANT: The constructor of any subclass of this abstract class, should never call any of its child Selector's Iterator.hasNext() or Iterator.next() methods, because that can cause descendant Selectors to be selected too early (which breaks MimicReplayingEntitySelector).
