java.lang.Object
  org.apache.jackrabbit.jcr2spi.util.ReferenceChangeTracker

public class ReferenceChangeTracker
extends Object

Simple helper class that can be used to keep track of uuid mappings (e.g. if the uuid of an imported or copied node is mapped to a new uuid) and processed (e.g. imported or copied) reference properties that might need correcting depending on the uuid mappings.

Constructor Summary

ReferenceChangeTracker()
Creates a new instance.

Method Summary

void	clear() Resets all internal state.
QValue	getMappedReference(QValue oldReference, QValueFactory factory) Returns the new UUID to which oldUUID has been mapped or null if no such mapping exists.
Iterator<PropertyState>	getReferences()
void	mappedUUIDs(String oldUUID, String newUUID) Store the given uuid mapping for later lookup using #adjustReferences(UpdatableItemStateManager, ItemStateValidator).
void	processedReference(PropertyState refPropertyState) Store the given reference property for later resolution.
