                  org.optaplanner.core.impl.heuristic.selector.move.decorator.CachingMoveSelector

All Implemented Interfaces:
  Iterable<Move>, EventListener, SelectionCacheLifecycleListener, IterableSelector<Move>, MoveSelector, Selector, PhaseLifecycleListener, SolverLifecycleListener

    public class CachingMoveSelector

extends AbstractCachingMoveSelector

A `MoveSelector` that caches the result of its child `MoveSelector`.

Keep this code in sync with `CachingEntitySelector` and `CachingValueSelector`.

Constructor Summary
`CachingMoveSelector(MoveSelector childMoveSelector, SelectionCacheType cacheType, boolean randomSelection)`

Method Summary
`boolean` | `isNeverEnding()` Is true if `Selector.isCountable()` is false or if this selector is in random order (for most cases).

Field Detail

### randomSelection

    protected final boolean randomSelection

Constructor Detail

### CachingMoveSelector

    public CachingMoveSelector(MoveSelector childMoveSelector,
                               SelectionCacheType cacheType,
                               boolean randomSelection)

Method Detail

### isNeverEnding

    public boolean isNeverEnding()

  Description copied from interface: `Selector`
  Is true if `Selector.isCountable()` is false or if this selector is in random order (for most cases). Is never true when this selector is in shuffled order (which is less scalable but more exact).

  Returns:
    true if the `Iterator.hasNext()` of the `Iterator` created by `Iterable.iterator()` never returns false (except when it's empty).

### iterator

    public Iterator<Move> iterator()

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`
