getCacheType
Description copied from interface:Selector
Unless this selector itself caches, this returnsSelectionCacheType.JUST_IN_TIME
, even if a selector child caches.- Specified by:
getCacheType
in interfaceSelector<Solution_>
- Overrides:
getCacheType
in classAbstractSelector<Solution_>
- Returns:
- never null
-
supportsPhaseAndSolverCaching
public boolean supportsPhaseAndSolverCaching()- Specified by:
supportsPhaseAndSolverCaching
in interfaceMoveSelector<Solution_>
-
constructCache
- Specified by:

in interfaceSelectionCacheLifecycleListener<Solution_>
-
disposeCache
- Specified by:

in interfaceSelectionCacheLifecycleListener<Solution_>
-
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)
-
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_>
- Returns:
- true if the
Iterator.hasNext()
of theIterator
created byIterable.iterator()
never returns false (except when it's empty).
-
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
