SelectionCacheType |
getCacheType()
Unless this selector itself caches, this returns
SelectionCacheType.JUST_IN_TIME ,
even if a selector child caches. |
ValueSelector |
getChildValueSelector() |
long |
getSize() |
long |
getSize(Object entity)
Similar to
IterableSelector.getSize() , but requires an entity. |
PlanningVariableDescriptor |
getVariableDescriptor() |
boolean |
isContinuous()
If true, then
Selector.isNeverEnding() is also true. |
