public abstract class WrappingUnfilteredRowIterator extends com.google.common.collect.UnmodifiableIterator<Unfiltered> implements UnfilteredRowIterator
Note that if most of what you want to do is modifying/filtering the returned
Unfiltered
, Transformation.apply(UnfilteredRowIterator,Transformation)
can be a simpler option.
