Constructor Detail

SortingMoveSelector

public SortingMoveSelector(MoveSelector childMoveSelector,
                   SelectionCacheType cacheType,
                   SelectionSorter sorter)

Method Detail

constructCache

public void constructCache(DefaultSolverScope solverScope)

Specified by:

constructCache in interface SelectionCacheLifecycleListener

Overrides:

constructCache in class AbstractCachingMoveSelector

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
