Method Details
-
isCountable
boolean isCountable()If false, thenisNeverEnding()
is true.- Returns:
- true if all the
ValueRange
s are countable (for example a double value range between 1.2 and 1.4 is not countable)
-
isNeverEnding
boolean isNeverEnding()Is true ifisCountable()
is false 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).- Returns:
- true if the
Iterator.hasNext()
of theIterator
created byIterable.iterator()
never returns false (except when it's empty).
-
getCacheType
SelectionCacheType getCacheType()Unless this selector itself caches, this returnsSelectionCacheType.JUST_IN_TIME
, even if a selector child caches.- Returns:
- never null
