AbstractCachingValueSelector
public AbstractCachingValueSelector(EntityIndependentValueSelector childValueSelector,
SelectionCacheType cacheType)
getChildValueSelector
public ValueSelector getChildValueSelector()
getCacheType
public SelectionCacheType getCacheType()
- Description copied from interface:
Selector
- Unless this selector itself caches, this returns
SelectionCacheType.JUST_IN_TIME
,
even if a selector child caches.
- Specified by:
getCacheType
in interface Selector
- Overrides:
getCacheType
in class AbstractSelector
- Returns:
- never null
constructCache
public void constructCache(DefaultSolverScope solverScope)
- Specified by:
constructCache
in interface SelectionCacheLifecycleListener
disposeCache
public void disposeCache(DefaultSolverScope solverScope)
- Specified by:
disposeCache
in interface SelectionCacheLifecycleListener
getVariableDescriptor
public PlanningVariableDescriptor getVariableDescriptor()
- Specified by:
getVariableDescriptor
in interface ValueSelector
- Returns:
- never null
isContinuous
public boolean isContinuous()
- Description copied from interface:
Selector
- If true, then
Selector.isNeverEnding()
is also true.
- Specified by:
isContinuous
in interface Selector
- Returns:
- true if any of the value ranges are continuous (as in for example every double value between 1.2 and 1.4)
getSize
public long getSize(Object entity)
- Description copied from interface:
ValueSelector
- Similar to
IterableSelector.getSize()
, but requires an entity.
- Specified by:
getSize
in interface ValueSelector
- Parameters:
entity
- never null
- Returns:
- the approximate number of elements generated by this
Selector
, always >= 0
getSize
public long getSize()
