Class RelativeStepFilter

public class RelativeStepFilter extends FilterConsumer implements PositionConsumer

Used to filter the output of RelativeStep. Atomic values are passed though as-is, while node values are sorted by document order and duplicates removed. An exception is thrown if there is a mix of atoms and nodes. Informally: {@code E1/E2} is implemented as: {@code RelativeStepFilter(for $dot in E1 return E2)}.
