Modifier and Type | Method and Description |

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(Object entity)
Similar to
IterableSelector.getSize() , but requires an entity. |
GenuineVariableDescriptor |
getVariableDescriptor() |
boolean |
isCountable()
If false, then
Selector.isNeverEnding() is true. |
boolean |
isNeverEnding()
Is true if
Selector.isCountable() is false
or if this selector is in random order (for most cases). |
Iterator<Object> |
iterator(Object entity)
Similar to
Iterable.iterator() , but requires an entity. |

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).Iterator.hasNext()
of the Iterator
created by Iterable.iterator()
never returns false (except when it's empty).public Iterator<Object> iterator(Object entity)

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.entity
