EntityIndependentFilteringValueSelector

public EntityIndependentFilteringValueSelector(EntityIndependentValueSelector<Solution_> childValueSelector,

Method Detail

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<Solution_,Object>

Returns:

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

iterator

public Iterator<Object> iterator()

Specified by:

iterator in interface Iterable<Solution_>

determineBailOutSize

protected long determineBailOutSize()
