Method Detail

castReplayingSelector

protected MimicReplayingValueSelector<Solution_> castReplayingSelector(Object uncastReplayingSelector)

Specified by:

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

createDemand

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

Specified by:

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

iterator

public Iterator<ElementRef> iterator()

Specified by:

iterator in interface Iterable<Solution_>

solvingStarted

public void solvingStarted(SolverScope<Solution_> solverScope)

Specified by:

solvingStarted in interface SolverLifecycleListener<Solution_>

Overrides:

solvingStarted in class AbstractSelector<Solution_>

computeDestinationSize

protected int computeDestinationSize()

solvingEnded

public void solvingEnded(SolverScope<Solution_> solverScope)

Specified by:

solvingEnded in interface SolverLifecycleListener<Solution_>

Overrides:

solvingEnded in class AbstractSelector<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_,ReplayingSelector_ extends PhaseLifecycleListener<Solution_>>

Returns:

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

elementRef

protected ElementRef elementRef(Object next)
