Method Detail

addMimicReplayingEntitySelector
public void addMimicReplayingEntitySelector(MimicReplayingEntitySelector<Solution_> replayingEntitySelector)
- Specified by:
addMimicReplayingEntitySelectorin interfaceEntityMimicRecorder<Solution_>- Parameters:
replayingEntitySelector- never null
-
getEntityDescriptor
public EntityDescriptor<Solution_> getEntityDescriptor()
- Specified by:
getEntityDescriptorin interfaceEntityMimicRecorder<Solution_>- Specified by:
getEntityDescriptorin interfaceEntitySelector<Solution_>- Returns:
- As defined by
EntitySelector.getEntityDescriptor() - See Also:
EntitySelector.getEntityDescriptor()
-
isCountable
public boolean isCountable()
Description copied from interface:SelectorIf false, thenSelector.isNeverEnding()is true.- Specified by:
isCountablein interfaceEntityMimicRecorder<Solution_>- Specified by:
isCountablein interfaceSelector<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 interfaceEntityMimicRecorder<Solution_>- Specified by:
isNeverEndingin interfaceSelector<Solution_>- Returns:
- As defined by
Selector.isNeverEnding() - See Also:
Selector.isNeverEnding()
-
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 interfaceEntityMimicRecorder<Solution_>- Specified by:
getSizein interfaceIterableSelector<Solution_,Object>- Returns:
- As defined by
IterableSelector.getSize() - See Also:
IterableSelector.getSize()
-
endingIterator
public Iterator<Object> endingIterator()
Description copied from interface:EntitySelectorIfSelector.isNeverEnding()is true, thenIterable.iterator()will never end. This returns an endingIterator, that tries to matchIterable.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 thisEntitySelectorentirely.- Specified by:
endingIteratorin interfaceEntityMimicRecorder<Solution_>- Specified by:
endingIteratorin interfaceEntitySelector<Solution_>- Returns:
- As defined by
EntitySelector.endingIterator() - See Also:
EntitySelector.endingIterator()
-
listIterator
public ListIterator<Object> listIterator()
- Specified by:
listIteratorin interfaceListIterable<Solution_>- Returns:
- never null, see
List.listIterator(). - See Also:
List.listIterator()
-
listIterator
public ListIterator<Object> listIterator(int index)
- Specified by:
listIteratorin interfaceListIterable<Solution_>- Parameters:
index- lower than the size of thisListIterable, seeList.listIterator(int).- Returns:
- never null, see
List.listIterator(int). - See Also:
List.listIterator()
