identifier of this NodeReferences instance.

references

protected java.util.ArrayList references

list of PropertyId's (i.e. the id's of the properties that refer to the target node denoted by id.getTargetId()).

note that the list can contain duplicate entries because a specific REFERENCE property can contain multiple references (if it's multi-valued) to potentially the same target node.
