Constructor Details

NearSubListNearbyDestinationSelector

public NearSubListNearbyDestinationSelector(ElementDestinationSelector<Solution_> childDestinationSelector,
 SubListSelector<Solution_> originSubListSelector,
 NearbyDistanceMeter<?,?> nearbyDistanceMeter,
 NearbyRandom nearbyRandom,
 boolean randomSelection)

Method Details

castReplayingSelector

protected MimicReplayingSubListSelector<Solution_> castReplayingSelector(Object uncastReplayingSelector)

Specified by:

castReplayingSelector in class AbstractNearbySelector<Solution_,ElementDestinationSelector<Solution_>,MimicReplayingSubListSelector<Solution_>>

createDemand

protected AbstractNearbyDistanceMatrixDemand<?,?,?,?> createDemand()

Specified by:

createDemand in class AbstractNearbySelector<Solution_,ElementDestinationSelector<Solution_>,MimicReplayingSubListSelector<Solution_>>

solvingStarted

public void solvingStarted(SolverScope<Solution_> solverScope)

Specified by:

solvingStarted in interface SolverLifecycleListener<Solution_>

Overrides:

solvingStarted in class AbstractNearbySelector<Solution_,ElementDestinationSelector<Solution_>,MimicReplayingSubListSelector<Solution_>>

solvingEnded

public void solvingEnded(SolverScope<Solution_> solverScope)

Specified by:

solvingEnded in interface SolverLifecycleListener<Solution_>

Overrides:

solvingEnded in class AbstractNearbySelector<Solution_,ElementDestinationSelector<Solution_>,MimicReplayingSubListSelector<Solution_>>

isCountable

public boolean isCountable()

Description copied from interface: Selector

If false, then Selector.isNeverEnding() is true.

Specified by:

isCountable in interface Selector<Solution_>

Returns:

true if all the ValueRanges are countable (for example a double value range between 1.2 and 1.4 is not countable)

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.

Specified by:

getSize in interface IterableSelector<Solution_,ElementRef>

Returns:

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

iterator

public Iterator<ElementRef> iterator()

Specified by:

iterator in interface Iterable<Solution_>
