addMimicReplayingValueSelector
public void addMimicReplayingValueSelector(MimicReplayingValueSelector<Solution_> replayingValueSelector) - Specified by:
addMimicReplayingValueSelector
in interfaceValueMimicRecorder<Solution_>
- Parameters:
replayingValueSelector
- never null
-
getVariableDescriptor
- Specified by:
getVariableDescriptor
in interfaceValueMimicRecorder<Solution_>
- Specified by:
getVariableDescriptor
in interfaceValueSelector<Solution_>
- Returns:
- As defined by
ValueSelector.getVariableDescriptor()
- See Also:
-
isCountable
public boolean isCountable()Description copied from interface:Selector
If false, thenSelector.isNeverEnding()
is true.- Specified by:
isCountable
in interfaceSelector<Solution_>
- Specified by:
isCountable
in interfaceValueMimicRecorder<Solution_>
- Returns:
- As defined by
Selector.isCountable()
- See Also:
-
isNeverEnding
public boolean isNeverEnding()Description copied from interface:Selector
Is true ifSelector.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 interfaceSelector<Solution_>
- Specified by:
isNeverEnding
in interfaceValueMimicRecorder<Solution_>
- Returns:
- As defined by
Selector.isNeverEnding()
- See Also:
-
getSize
Description copied from interface:ValueSelector
Similar toIterableSelector.getSize()
, but requires an entity.- Specified by:
getSize
in interfaceValueMimicRecorder<Solution_>
- Specified by:
getSize
in interfaceValueSelector<Solution_>
- Parameters:
entity
- never null- Returns:
- As defined by
ValueSelector.getSize(Object)
- See Also:
-
getSize
public long getSize()Description copied from interface:IterableSelector
A random JITSelector
withSelector.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 inSelectionProbabilityWeightFactory
.- Specified by:
getSize
in interfaceIterableSelector<Solution_,
Object> - Specified by:
getSize
in interfaceValueMimicRecorder<Solution_>
- Returns:
- As defined by
IterableSelector.getSize()
- See Also:
-
iterator
Description copied from interface:ValueSelector
Similar toIterable.iterator()
, but requires an entity.- Specified by:
iterator
in interfaceValueSelector<Solution_>
- Parameters:
entity
- never null- Returns:
- never null
-
iterator
-
endingIterator
Description copied from interface:ValueSelector
IfSelector.isNeverEnding()
is true, thenValueSelector.iterator(Object)
will never end. This returns an endingIterator
, that tries to matchValueSelector.iterator(Object)
as much as possible, but return each distinct element only once and therefore it might not respect the configuration of thisValueSelector
entirely.- Specified by:
endingIterator
in interfaceValueMimicRecorder<Solution_>
- Specified by:
endingIterator
in interfaceValueSelector<Solution_>
- Parameters:
entity
- never null- Returns:
- As defined by
ValueSelector.endingIterator(Object)
