Class ReferenceChangeTracker

  • public class ReferenceChangeTracker
extends java.lang.Object
    Helper class 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 to be adjusted depending on the UUID mapping resulting from the import.
