Iterator<Object> |
endingIterator()
If
Selector.isNeverEnding() is true, then Iterable.iterator() will never end. |
SelectionCacheType |
getCacheType()
Unless this selector itself caches, this returns
SelectionCacheType.JUST_IN_TIME ,
even if a selector child caches. |
EntityDescriptor |
getEntityDescriptor() |

getSize()
A random JIT
Selector with Selector.isNeverEnding() true should return a size
as if it would be able to return each distinct element only once,
because the size can be used in SelectionProbabilityWeightFactory . |
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). |

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