Method Detail

addMimicReplayingValueSelector
public void addMimicReplayingValueSelector(MimicReplayingValueSelector<Solution_> replayingEntitySelector)
- Specified by:
addMimicReplayingValueSelectorin interfaceValueMimicRecorder<Solution_>- Parameters:
replayingEntitySelector- never null
-
getVariableDescriptor
public GenuineVariableDescriptor<Solution_> getVariableDescriptor()
- Specified by:
getVariableDescriptorin interfaceValueMimicRecorder<Solution_>- Specified by:
getVariableDescriptorin interfaceValueSelector<Solution_>- Returns:
- As defined by
ValueSelector.getVariableDescriptor() - See Also:
ValueSelector.getVariableDescriptor()
-
isCountable
public boolean isCountable()
Description copied from interface:SelectorIf false, thenSelector.isNeverEnding()is true.- Specified by:
isCountablein interfaceSelector<Solution_>- Specified by:
isCountablein interfaceValueMimicRecorder<Solution_>- Returns:
- As defined by
Selector.isCountable() - See Also:
Selector.isCountable()
-
isNeverEnding
public boolean isNeverEnding()
Description copied from interface:SelectorIs 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:
isNeverEndingin interfaceSelector<Solution_>- Specified by:
isNeverEndingin interfaceValueMimicRecorder<Solution_>- Returns:
- As defined by
Selector.isNeverEnding() - See Also:
Selector.isNeverEnding()
-
getSize
public long getSize(Object entity)
Description copied from interface:ValueSelectorSimilar toIterableSelector.getSize(), but requires an entity.- Specified by:
getSizein interfaceValueMimicRecorder<Solution_>- Specified by:
getSizein interfaceValueSelector<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:IterableSelectorA random JITSelectorwithSelector.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:
getSizein interfaceIterableSelector<Solution_,Object>- Specified by:
getSizein interfaceValueMimicRecorder<Solution_>- Returns:
- As defined by
IterableSelector.getSize() - See Also:
IterableSelector.getSize()
-
iterator
public Iterator<Object> iterator(Object entity)
Description copied from interface:ValueSelectorSimilar toIterable.iterator(), but requires an entity.- Specified by:
iteratorin interfaceValueSelector<Solution_>- Parameters:
entity- never null- Returns:
- never null
-
endingIterator
public Iterator<Object> endingIterator(Object entity)
Description copied from interface:ValueSelectorIfSelector.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 thisValueSelectorentirely.- Specified by:
endingIteratorin interfaceValueMimicRecorder<Solution_>- Specified by:
endingIteratorin interfaceValueSelector<Solution_>- Parameters:
entity- never null- Returns:
- As defined by
ValueSelector.endingIterator(Object) - See Also:
ValueSelector.endingIterator(Object)
