SelectedCountLimitValueSelector(ValueSelector childValueSelector,
long selectedCountLimit)
Unlike most of the other
ValueSelector decorations,
this one works for an entity dependent ValueSelector too. |
| Modifier and Type | Method and Description |
|---|---|
Iterator<Object> |
endingIterator(Object entity)
If
Selector.isNeverEnding() is true, then ValueSelector.iterator(Object) will never end. |
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. |
long |
getSize(Object entity)
Similar to
IterableSelector.getSize(), but requires an entity. |
GenuineVariableDescriptor |
getVariableDescriptor() |
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). |

ValueSelectorSelector.isNeverEnding() is true, then ValueSelector.iterator(Object) will never end.
This returns an ending Iterator, that tries to match ValueSelector.iterator(Object) as much as possible,
but return each distinct element only once
and therefore it might not respect the configuration of this ValueSelector entirely.endingIterator in interface ValueSelectorentity - never nullValueSelector.iterator(Object)Copyright © 2006–2021 JBoss by Red Hat. All rights reserved.
