com.github.basking2.sdsai.itrex.iterators.splitjoin.MappingUncertainIterator<T,R>

All Implemented Interfaces:

UncertainIterator<R>

public class MappingUncertainIterator<T,R>
extends Object
implements UncertainIterator<R>

This does just what MappingIterator does but for UncertainIterator objects. The mapping function must define a result.
