getCacheType
Description copied from interface:Selector
Unless this selector itself caches, this returnsSelectionCacheType.JUST_IN_TIME
, even if a selector child caches.- Specified by:

in interfaceSelector<Solution_>
- Overrides:

in classAbstractSelector<Solution_>
- Returns:
- never null

isCountable
public boolean isCountable()Description copied from interface:Selector
If false, thenSelector.isNeverEnding()
is true.- Specified by:
isCountable
in interfaceSelector<Solution_>
- Returns:
- true if all the
ValueRange
s are countable (for example a double value range between 1.2 and 1.4 is not countable)
-
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
.
