org.chromattic.core.jcr
Class ReferenceLinkManager

java.lang.Object
  org.chromattic.core.jcr.AbstractLinkManager
      org.chromattic.core.jcr.ReferenceLinkManager

public class ReferenceLinkManager
extends AbstractLinkManager

The reference manager takes care of managing references between nodes. The main reason is that JCR reference management is a bit weird about the usage of Node#getReferences(). The goal of this class is to manage one to many relationships between nodes and their consistency.

The life time of this object is valid from the beginning of the session until the session or a portion of the session is saved. When a session is saved, the clear operation will reset the state of the reference manager.
