Method Summary

Modifier and Type	Method	Description
void	addMimicReplayingValueSelector(MimicReplayingValueSelector<Solution_> replayingValueSelector)
Iterator<Object>	endingIterator(Object entity)	If Selector.isNeverEnding() is true, then ValueSelector.iterator(Object) will never end.
boolean	equals(Object other)
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.
long	getSize(Object entity)	Similar to IterableSelector.getSize(), but requires an entity.
GenuineVariableDescriptor<Solution_>	getVariableDescriptor()
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).
Iterator<Object>	iterator()
Iterator<Object>	iterator(Object entity)	Similar to Iterable.iterator(), but requires an entity.
String	toString()

MimicRecordingValueSelector

public MimicRecordingValueSelector(EntityIndependentValueSelector<Solution_> childValueSelector)

Method Details

addMimicReplayingValueSelector

public void addMimicReplayingValueSelector(MimicReplayingValueSelector<Solution_> replayingValueSelector)

Specified by:

addMimicReplayingValueSelector in interface ValueMimicRecorder<Solution_>

Parameters:

replayingValueSelector - never null

getVariableDescriptor

public GenuineVariableDescriptor<Solution_> getVariableDescriptor()

Specified by:

getVariableDescriptor in interface ValueMimicRecorder<Solution_>

Specified by:

getVariableDescriptor in interface ValueSelector<Solution_>

Returns:

As defined by ValueSelector.getVariableDescriptor()

See Also:

• ValueSelector.getVariableDescriptor()

isCountable

public boolean isCountable()

Description copied from interface: Selector

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

Specified by:

isCountable in interface Selector<Solution_>

Specified by:

isCountable in interface ValueMimicRecorder<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 Selector<Solution_>

Specified by:

isNeverEnding in interface ValueMimicRecorder<Solution_>

Returns:

As defined by Selector.isNeverEnding()

See Also:

• Selector.isNeverEnding()

getSize

public long getSize(Object entity)

Description copied from interface: ValueSelector

Similar to IterableSelector.getSize(), but requires an entity.

Specified by:

getSize in interface ValueMimicRecorder<Solution_>

Specified by:

getSize in interface ValueSelector<Solution_>

Parameters:

entity - never null

Returns:

As defined by ValueSelector.getSize(Object)

See Also:

• ValueSelector.getSize(Object)

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_,Object>

Specified by:

getSize in interface ValueMimicRecorder<Solution_>

Returns:

As defined by IterableSelector.getSize()

See Also:

• IterableSelector.getSize()

iterator

public Iterator<Object> iterator(Object entity)

Description copied from interface: ValueSelector

Similar to Iterable.iterator(), but requires an entity.

Specified by:

iterator in interface ValueSelector<Solution_>

Parameters:

entity - never null

Returns:

never null

iterator

public Iterator<Object> iterator()

Specified by:

iterator in interface Iterable<Solution_>

endingIterator

public Iterator<Object> endingIterator(Object entity)

Description copied from interface: ValueSelector

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

Specified by:

endingIterator in interface ValueMimicRecorder<Solution_>

Specified by:

endingIterator in interface ValueSelector<Solution_>

Parameters:

entity - never null

Returns:

As defined by ValueSelector.endingIterator(Object)

See Also:

• ValueSelector.endingIterator(Object)

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
