Method Summary

Modifier and Type	Method	Description
long	getSize()	Deprecated, for removal: This API element is subject to removal in a future version. 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	isCountable()	Deprecated, for removal: This API element is subject to removal in a future version. If false, then Selector.isNeverEnding() is true.
boolean	isNeverEnding()	Deprecated, for removal: This API element is subject to removal in a future version. Is true if Selector.isCountable() is false or if this selector is in random order (for most cases).
Iterator<Move<Solution_>>	iterator()	Deprecated, for removal: This API element is subject to removal in a future version.
void	solvingEnded(SolverScope<Solution_> solverScope)	Deprecated, for removal: This API element is subject to removal in a future version.

Constructor Details

TailChainSwapMoveSelector

public TailChainSwapMoveSelector(EntitySelector<Solution_> entitySelector,
 ValueSelector<Solution_> valueSelector,
 boolean randomSelection)

Deprecated, for removal: This API element is subject to removal in a future version.

Method Details

solvingStarted

public void solvingStarted(SolverScope<Solution_> solverScope)

Deprecated, for removal: This API element is subject to removal in a future version.

Specified by:

solvingStarted in interface SolverLifecycleListener<Solution_>

Overrides:

solvingStarted in class AbstractSelector<Solution_>

solvingEnded

public void solvingEnded(SolverScope<Solution_> solverScope)

Deprecated, for removal: This API element is subject to removal in a future version.

Specified by:

solvingEnded in interface SolverLifecycleListener<Solution_>

Overrides:

solvingEnded in class AbstractSelector<Solution_>

isCountable

public boolean isCountable()

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from interface: Selector

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

Returns:

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

isNeverEnding

public boolean isNeverEnding()

Deprecated, for removal: This API element is subject to removal in a future version.

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).

getSize

public long getSize()

Deprecated, for removal: This API element is subject to removal in a future version.

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<Solution_>> iterator()

Deprecated, for removal: This API element is subject to removal in a future version.

toString

public String toString()

Deprecated, for removal: This API element is subject to removal in a future version.

Overrides:

toString in class Object
