If

getSize(Object entity)
Similar to
IterableSelector.getSize() , but requires an entity. |

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 entity)
Similar to
Iterable.iterator() , but requires an entity. |

Is never true when this selector is in shuffled order (which is less scalable but more exact).Iterator.hasNext()

never returns false (except when it's empty).public long getSize(Object entity)

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.entity
