Method Detail

phaseStarted
public void phaseStarted(AbstractPhaseScope<Solution_> phaseScope)
- Specified by:
phaseStartedin interfacePhaseLifecycleListener<Solution_>- Overrides:
phaseStartedin classAbstractSelector<Solution_>
-
phaseEnded
public void phaseEnded(AbstractPhaseScope<Solution_> phaseScope)
- Specified by:
phaseEndedin interfacePhaseLifecycleListener<Solution_>- Overrides:
phaseEndedin classAbstractSelector<Solution_>
-
getVariableDescriptor
public GenuineVariableDescriptor<Solution_> getVariableDescriptor()
- Specified by:
getVariableDescriptorin interfaceValueSelector<Solution_>- Returns:
- never null
-
isCountable
public boolean isCountable()
Description copied from interface:SelectorIf false, thenSelector.isNeverEnding()is true.- Specified by:
isCountablein interfaceSelector<Solution_>- 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:SelectorIs 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).- Specified by:
isNeverEndingin interfaceSelector<Solution_>- Returns:
- true if the
Iterator.hasNext()of theIteratorcreated byIterable.iterator()never returns false (except when it's empty).
-
getSize
public long getSize(Object entity)
Description copied from interface:ValueSelectorSimilar toIterableSelector.getSize(), but requires an entity.- Specified by:
getSizein interfaceValueSelector<Solution_>- Parameters:
entity- never null- Returns:
- the approximate number of elements generated by this
Selector, always>= 0
-
getSize
public long getSize()
Description copied from interface:IterableSelectorA random JITSelectorwithSelector.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.- Specified by:
getSizein interfaceIterableSelector<Solution_,Object>- Returns:
- the approximate number of elements generated by this
Selector, always>= 0
-
iterator
public Iterator<Object> iterator(Object entity)
Description copied from interface:ValueSelectorSimilar toIterable.iterator(), but requires an entity.- Specified by:
iteratorin interfaceValueSelector<Solution_>- Parameters:
entity- never null- Returns:
- never null
-
recordedHasNext
public void recordedHasNext(boolean hasNext)
-
recordedNext
public void recordedNext(Object next)
-
endingIterator
public Iterator<Object> endingIterator(Object entity)
Description copied from interface:ValueSelectorIfSelector.isNeverEnding()is true, thenValueSelector.iterator(Object)will never end. This returns an endingIterator, that tries to matchValueSelector.iterator(Object)as much as possible, but return each distinct element only once and therefore it might not respect the configuration of thisValueSelectorentirely.- Specified by:
endingIteratorin interfaceValueSelector<Solution_>- Parameters:
entity- never null- Returns:
- never null
