All known Subclasses: gnu.xquery.util.RelativeStepFilter, gnu.lists.TreeList, gnu.xml.XMLPrinter, gnu.xml.XMLFilter,
| PositionConsumer | | public interface PositionConsumer (Code) | | 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 | |
| public void | consume(SeqPosition position)
Consume node at current position. | | public void | writePosition(AbstractSequence seq, int ipos)
Consume a single position pair.
This PositionConsumer may assume the sequence does no reference
management; i.e. |
| consume | | public void consume(SeqPosition position)(Code) | | 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 | | public void writePosition(AbstractSequence seq, int ipos)(Code) | | 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.
