- All Implemented Interfaces:
- Iterable<Object>, EventListener, SelectionCacheLifecycleListener, IterableSelector<Object>, Selector, EntityIndependentValueSelector, ValueSelector, PhaseLifecycleListener, SolverLifecycleListener
public class ShufflingValueSelector
- extends AbstractCachingValueSelector
- implements EntityIndependentValueSelector
ShufflingValueSelector
public ShufflingValueSelector(EntityIndependentValueSelector childValueSelector,
SelectionCacheType cacheType)
isNeverEnding
public boolean isNeverEnding()
- Description copied from interface:
Selector
- Is true if
Selector.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).
- Specified by:
isNeverEnding
in interface Selector
- Returns:
- true if the
Iterator.hasNext()
of the Iterator
created by Iterable.iterator()
never returns false (except when it's empty).
iterator
public Iterator<Object> iterator(Object entity)
- Description copied from interface:
ValueSelector
- Similar to
Iterable.iterator()
, but requires an entity.
- Specified by:
iterator
in interface ValueSelector
- Parameters:
entity
- never null
- Returns:
- never null
iterator
public Iterator<Object> iterator()
- Specified by:
iterator
in interface Iterable<Object>
toString
public String toString()
- Overrides:
