- All Implemented Interfaces:
- Iterable<Move>, EventListener, SelectionCacheLifecycleListener, IterableSelector<Move>, MoveSelector, Selector, PhaseLifecycleListener, SolverLifecycleListener
public class MoveListFactoryToMoveSelectorBridge
- extends AbstractMoveSelector
- implements SelectionCacheLifecycleListener
Bridges a MoveListFactory to a MoveSelector.

MoveListFactoryToMoveSelectorBridge
public MoveListFactoryToMoveSelectorBridge(MoveListFactory moveListFactory,
SelectionCacheType cacheType,
boolean randomSelection)
getCacheType
public SelectionCacheType getCacheType()
- Description copied from interface:
Selector
- Unless this selector itself caches, this returns
SelectionCacheType.JUST_IN_TIME,
even if a selector child caches.
- Specified by:
getCacheType in interface Selector- Overrides:
getCacheType in class AbstractSelector
- Returns:
- never null
constructCache
public void constructCache(DefaultSolverScope solverScope)
- Specified by:
constructCache in interface SelectionCacheLifecycleListener
disposeCache
public void disposeCache(DefaultSolverScope solverScope)
- Specified by:
disposeCache in interface SelectionCacheLifecycleListener
isCountable
public boolean isCountable()
- Description copied from interface:
Selector
- If false, then
Selector.isNeverEnding() is true.
- Specified by:
isCountable in interface Selector
- 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:
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).
getSize
public long getSize()
- Description copied from interface:
IterableSelector
- 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.
- Specified by:
getSize in interface IterableSelector<Move>
- Returns:
- the approximate number of elements generated by this
Selector, always >= 0
iterator
public Iterator<Move> iterator()
- Specified by:
iterator in interface Iterable<Move>
toString
public String toString()
- Overrides:
toString in class Object
