Constructor Summary

Method Summary
 Iterator<Object> endingIterator()
          If Selector.isNeverEnding() is true, then Iterable.iterator() will never end.
 PlanningEntityDescriptor getEntityDescriptor()
           
 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.
 boolean isContinuous()
          If true, then Selector.isNeverEnding() is also true.
 boolean isNeverEnding()
          Is true if Selector.isContinuous() is true or if this selector is in random order (for most cases).

protected Object recording

recordingAlreadyReturned

Constructor Detail

MimicReplayingEntitySelector

public MimicReplayingEntitySelector(MimicRecordingEntitySelector recordingEntitySelector)
Method Detail

phaseStarted

public void phaseStarted(AbstractSolverPhaseScope phaseScope)
Specified by:
phaseStarted in interface SolverPhaseLifecycleListener
Overrides:
phaseStarted in class AbstractSelector

phaseEnded

public void phaseEnded(AbstractSolverPhaseScope phaseScope)
Specified by:
phaseEnded in interface SolverPhaseLifecycleListener
Overrides:
phaseEnded in class AbstractSelector

getEntityDescriptor

public PlanningEntityDescriptor getEntityDescriptor()
Returns:
never null

isContinuous

public boolean isContinuous()
Description copied from interface: Selector
If true, then Selector.isNeverEnding() is also true.

Returns:
true if any of the value ranges are continuous (as in for example every double value between 1.2 and 1.4)

isNeverEnding

public boolean isNeverEnding()
Description copied from interface: Selector
Is true if Selector.isContinuous() is true 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 the Iterator created by Iterable.iterator() never returns false.

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.

Returns:
the approximate number of elements generated by this Selector, always >= 0

iterator

public Iterator<Object> iterator()

recordedHasNext

public void recordedHasNext(boolean hasNext)

recordedNext

public void recordedNext(Object next)

endingIterator

public Iterator<Object> endingIterator()
Description copied from interface: EntitySelector
If Selector.isNeverEnding() is true, then Iterable.iterator() will never end. This returns an ending Iterator, that tries to match Iterable.iterator() as much as possible, but might not respect the configuration of this EntitySelector entirely.

Returns:
never null
See Also:
Iterable.iterator()

listIterator

public ListIterator<Object> listIterator()
Description copied from interface: ListIterable
See List.listIterator()

Returns:
never null, see List.listIterator().

listIterator

public ListIterator<Object> listIterator(int index)
Description copied from interface: ListIterable
See List.listIterator()

Parameters:
index - lower than the size of this ListIterable, see List.listIterator(int).
Returns:
never null, see List.listIterator(int).

toString

public String toString()
Overrides:
toString in class Object
