getNearbyDistanceMatrixDemand

public final AbstractNearbyDistanceMatrixDemand<?,?,?,?> getNearbyDistanceMatrixDemand()

phaseStarted

public final void phaseStarted(AbstractPhaseScope<Solution_> phaseScope)

Specified by:

phaseStarted in interface PhaseLifecycleListener<Solution_>

Overrides:

phaseStarted in class AbstractSelector<Solution_>

phaseEnded

public void phaseEnded(AbstractPhaseScope<Solution_> phaseScope)

Specified by:

phaseEnded in interface PhaseLifecycleListener<Solution_>

Overrides:

phaseEnded in class AbstractSelector<Solution_>

isNeverEnding

public final 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).

equals

public final boolean equals(Object other)

Specified by:

equals in class AbstractDemandEnabledSelector<Solution_>

hashCode

public final int hashCode()

Specified by:

hashCode in class AbstractDemandEnabledSelector<Solution_>

toString

public final String toString()

Overrides:

toString in class Object
