getCacheType()
Unless this selector itself caches, this returns
SelectionCacheType.JUST_IN_TIME ,
even if a selector child caches. |
long |
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). |
