## org.optaplanner.core.impl.heuristic.selector.move.decorator
Class SelectedCountLimitMoveSelector

    java.lang.Object
      org.optaplanner.core.impl.heuristic.selector.AbstractSelector
          org.optaplanner.core.impl.heuristic.selector.move.AbstractMoveSelector
              org.optaplanner.core.impl.heuristic.selector.move.decorator.SelectedCountLimitMoveSelector

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

    public class SelectedCountLimitMoveSelector

extends AbstractMoveSelector

Field Summary
`protected MoveSelector` | `childMoveSelector`
`protected long` | `selectedCountLimit`

Fields inherited from class org.optaplanner.core.impl.heuristic.selector.AbstractSelector
`logger, phaseLifecycleSupport, workingRandom`

Constructor Summary
`SelectedCountLimitMoveSelector(MoveSelector childMoveSelector, long selectedCountLimit)`

Method Summary
`long` | `getSize()` A random JIT `Selector` with `Selector.isNeverEnding()` true should return a size as if it would be able to return each distinct element only once, because the size can be used in `SelectionProbabilityWeightFactory`.
`boolean` | `isCountable()` If false, then `Selector.isNeverEnding()` is true.
`boolean` | `isNeverEnding()` Is true if `Selector.isCountable()` is false or if this selector is in random order (for most cases).
`Iterator<Move>` | `iterator()`
`String` | `toString()`

Field Detail

### childMoveSelector

    protected final MoveSelector childMoveSelector

### selectedCountLimit

    protected final long selectedCountLimit

Constructor Detail

### SelectedCountLimitMoveSelector

    public SelectedCountLimitMoveSelector(MoveSelector childMoveSelector,
                                          long selectedCountLimit)

Method Detail

### isCountable

    public boolean isCountable()

  Description copied from interface: `Selector`
  If false, then `Selector.isNeverEnding()` is true.

  Returns:
    true if all the `ValueRange`s are countable (for example a double value range between 1.2 and 1.4 is not countable)

### 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).

### getSize

    public long getSize()

  Description copied from interface: `IterableSelector`
  A random JIT `Selector` with `Selector.isNeverEnding()` true should return a size as if it would be able to return each distinct element only once, because the size can be used in `SelectionProbabilityWeightFactory`.

  Returns:
    the approximate number of elements generated by this `Selector`, always >= 0

### iterator

    public Iterator<Move> iterator()

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`
