Method Detail

getCacheType
public SelectionCacheType getCacheType()
Description copied from interface:SelectorUnless this selector itself caches, this returnsSelectionCacheType.JUST_IN_TIME, even if a selector child caches.- Specified by:
getCacheTypein interfaceSelector<Solution_>- Overrides:
getCacheTypein classAbstractSelector<Solution_>- Returns:
- never null
-
supportsPhaseAndSolverCaching
public boolean supportsPhaseAndSolverCaching()
- Specified by:
supportsPhaseAndSolverCachingin interfaceMoveSelector<Solution_>
-
constructCache
public void constructCache(SolverScope<Solution_> solverScope)
- Specified by:
constructCachein interfaceSelectionCacheLifecycleListener<Solution_>
-
disposeCache
public void disposeCache(SolverScope<Solution_> solverScope)
- Specified by:
disposeCachein interfaceSelectionCacheLifecycleListener<Solution_>
-
isCountable
public boolean isCountable()
Description copied from interface:SelectorIf false, thenSelector.isNeverEnding()is true.- Specified by:
isCountablein interfaceSelector<Solution_>- Returns:
- true if all the
ValueRanges 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: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_>- Returns:
- true if the
Iterator.hasNext()of theIteratorcreated byIterable.iterator()never returns false (except when it's empty).
-
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.
