Method Details
-
getVariableDescriptor
- Specified by:
getVariableDescriptor
in interfaceValueSelector<Solution_>
- Returns:
- never null
-
castReplayingSelector
protected MimicReplayingValueSelector<Solution_> castReplayingSelector(Object uncastReplayingSelector) - Specified by:
castReplayingSelector
in classAbstractNearbySelector<Solution_,
EntityIndependentValueSelector<Solution_>, MimicReplayingValueSelector<Solution_>>
-
createDemand
- Specified by:
createDemand
in classAbstractNearbySelector<Solution_,
EntityIndependentValueSelector<Solution_>, MimicReplayingValueSelector<Solution_>>
-
isCountable
public boolean isCountable()Description copied from interface:Selector
If false, thenSelector.isNeverEnding()
is true.- Specified by:
isCountable
in interfaceSelector<Solution_>
- Returns:
- true if all the
ValueRange
s are countable (for example a double value range between 1.2 and 1.4 is not countable)
-
getSize
Description copied from interface:ValueSelector
Similar toIterableSelector.getSize()
, but requires an entity.- Specified by:
getSize
in 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:IterableSelector
A random JITSelector
withSelector.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:
getSize
in interfaceIterableSelector<Solution_,
Object> - Returns:
- the approximate number of elements generated by this
Selector
, always>= 0
-
iterator
Description copied from interface:ValueSelector
Similar toIterable.iterator()
, but requires an entity.- Specified by:
iterator
in interfaceValueSelector<Solution_>
- Parameters:
entity
- never null- Returns:
- never null
-
iterator
-
endingIterator
Description copied from interface:ValueSelector
IfSelector.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 thisValueSelector
entirely.- Specified by:
endingIterator
in interfaceValueSelector<Solution_>
- Parameters:
entity
- never null- Returns:
- never null
