EntityDescriptor<Solution_>	getEntityDescriptor()
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.
int	hashCode()
boolean	isCountable()	If false, then Selector.isNeverEnding() is true.
boolean	isNeverEnding()	Is true if Selector.isCountable() is false or if this selector is in random order (for most cases).

Method Details

addMimicReplayingEntitySelector

public void addMimicReplayingEntitySelector(MimicReplayingEntitySelector<Solution_> replayingEntitySelector)

Specified by:

addMimicReplayingEntitySelector in interface EntityMimicRecorder<Solution_>

Parameters:

replayingEntitySelector - never null

getEntityDescriptor

public EntityDescriptor<Solution_> getEntityDescriptor()

Specified by:

getEntityDescriptor in interface EntityMimicRecorder<Solution_>

Specified by:

getEntityDescriptor in interface EntitySelector<Solution_>

Returns:

As defined by EntitySelector.getEntityDescriptor()

See Also:

• EntitySelector.getEntityDescriptor()

isCountable

public boolean isCountable()

Description copied from interface: Selector

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

Specified by:

isCountable in interface EntityMimicRecorder<Solution_>

Specified by:

isCountable in interface Selector<Solution_>

Returns:

As defined by Selector.isCountable()

See Also:

• Selector.isCountable()

isNeverEnding

public 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).

Specified by:

isNeverEnding in interface EntityMimicRecorder<Solution_>

Specified by:

isNeverEnding in interface Selector<Solution_>

Returns:

As defined by Selector.isNeverEnding()

See Also:

• Selector.isNeverEnding()

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 EntityMimicRecorder<Solution_>

Specified by:

getSize in interface IterableSelector<Solution_,Object>

Returns:

As defined by IterableSelector.getSize()

See Also:

• IterableSelector.getSize()

iterator

public Iterator<Object> iterator()

Specified by:

iterator in interface Iterable<Solution_>

endingIterator

public Iterator<Object> endingIterator()

Description copied from interface: EntitySelector

If Selector.isNeverEnding() is true, then Iterable.iterator() will never end. This returns an ending Iterator, that tries to match Iterable.iterator() as much as possible, but returns each distinct element only once and returns every element that might possibly be selected and therefore it might not respect the configuration of this EntitySelector entirely.

Specified by:

endingIterator in interface EntityMimicRecorder<Solution_>

Specified by:

endingIterator in interface EntitySelector<Solution_>

Returns:

As defined by EntitySelector.endingIterator()

See Also:

• EntitySelector.endingIterator()

listIterator

public ListIterator<Object> listIterator()

Specified by:

listIterator in interface ListIterable<Solution_>

Returns:

never null, see List.listIterator().

See Also:

• List.listIterator()

listIterator

public ListIterator<Object> listIterator(int index)

Specified by:

listIterator in interface ListIterable<Solution_>

Parameters:

index - lower than the size of this ListIterable, see List.listIterator(int).

Returns:

never null, see List.listIterator(int).

See Also:

• List.listIterator()

equals

public boolean equals(Object other)

Specified by:

equals in class AbstractDemandEnabledSelector<Solution_>

hashCode

public int hashCode()

Specified by:

hashCode in class AbstractDemandEnabledSelector<Solution_>

toString

public String toString()

Overrides:

toString in class Object
