isCountable
public boolean isCountable()
Description copied from interface:SelectorIf false, thenSelector.isNeverEnding()is true.- Returns:
- true if all the
ValueRanges are countable (for example a double value range between 1.2 and 1.4 is not countable)
-
isNeverEnding
public boolean isNeverEnding()
Description copied from interface:SelectorIs true ifSelector.isCountable()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 theIteratorcreated byIterable.iterator()never returns false (except when it's empty).
-
getSize
public long getSize()
Description copied from interface:IterableSelectorA random JITSelectorwithSelector.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 inSelectionProbabilityWeightFactory.- Returns:
- the approximate number of elements generated by this
Selector, always>= 0
