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 isContinuous()
          If true, then Selector.isNeverEnding() is also true.
 boolean isNeverEnding()
          Is true if Selector.isContinuous() is true or if this selector is in random order (for most cases).

Constructor Detail

MoveIteratorFactoryToMoveSelectorBridge

public MoveIteratorFactoryToMoveSelectorBridge(MoveIteratorFactory moveIteratorFactory,
                                               boolean randomSelection)
Method Detail

phaseStarted

public void phaseStarted(AbstractSolverPhaseScope phaseScope)
Specified by:
phaseStarted in interface SolverPhaseLifecycleListener
Overrides:
phaseStarted in class AbstractSelector

phaseEnded

public void phaseEnded(AbstractSolverPhaseScope phaseScope)
Specified by:
phaseEnded in interface SolverPhaseLifecycleListener
Overrides:
phaseEnded in class AbstractSelector

isContinuous

public boolean isContinuous()
Description copied from interface: Selector
If true, then Selector.isNeverEnding() is also true.

Returns:
true if any of the value ranges are continuous (as in for example every double value between 1.2 and 1.4)

isNeverEnding

public boolean isNeverEnding()
Description copied from interface: Selector
Is true if Selector.isContinuous() is true 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.

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
