- Specified by:

- Overrides:

getEntityDescriptor
- Returns:
- never null
-
isCountable
public boolean isCountable()Description copied from interface:Selector
If false, thenSelector.isNeverEnding()
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
public boolean isNeverEnding()Description copied from interface:Selector
Is 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 theIterator
created byIterable.iterator()
never returns false (except when it's empty).
-
getSize
public long getSize()Description copied from interface:IterableSelector
A random JITSelector
withSelector.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
-
iterator
-
recordedHasNext
public void recordedHasNext(boolean hasNext) -
recordedNext
-
endingIterator
Description copied from interface:EntitySelector
IfSelector.isNeverEnding()
is true, thenIterable.iterator()
will never end. This returns an endingIterator
, that tries to matchIterable.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 thisEntitySelector
entirely.- Returns:
- never null
- See Also:
-
listIterator
- Returns:
- never null, see
List.listIterator()
. - See Also:
-
listIterator
- Parameters:
index
- lower than the size of thisListIterable
, seeList.listIterator(int)
.- Returns:
- never null, see
