Interface PositionConsumer

All Known Implementing Classes:

public interface PositionConsumer

An object that can be "fed" a TreePosition, and will do something with it. That "something" can be printing it, copy it, filter it - or ignore it.

Method Summary

Modifier and Type	Method and Description
void	writePosition(AbstractSequence seq, int ipos) Consume a single position pair.
void	writePosition(SeqPosition position) Consume node at current position.

Method Detail

writePosition

void writePosition(SeqPosition position)

Consume node at current position. The caller may invalidate or change the position after consume returns, so if the consumer wants to save it, it needs to copy it.

writePosition

void writePosition(AbstractSequence seq,
                   int ipos)

Consume a single position pair. This PositionConsumer may assume the sequence does no reference management; i.e. that copyPos is trivial and releasePos is a no-op. If that is not the case, use consume(TreePosition) instead.
