void |

disposeCache(DefaultSolverScope solverScope) |
Iterator<Object> |
endingIterator() |
Iterator<Object> |
endingIterator(Object entity)
If
Selector.isNeverEnding() is true, then ValueSelector.iterator(Object) will never end. |
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. |
GenuineVariableDescriptor |
getVariableDescriptor() |
boolean |
isCountable()
If false, then
Selector.isNeverEnding() is true. |

Selector.isNeverEnding()
is true, then ValueSelector.iterator(Object)
will never end.
This returns an ending Iterator
, that tries to match ValueSelector.iterator(Object)
as much as possible,
but return each distinct element only once
and therefore it might not respect the configuration of this ValueSelector
entirely.endingIterator
