Examples of org.modeshape.jcr.cache.SessionCache$PreSave

org.modeshape.jcr.cache.SessionCache
The definition of a callback that can be implemented and passed to {@link SessionCache#save(SessionCache,PreSave)} and{@link SessionCache#save(Set,SessionCache,PreSave)}, allowing the caller to recieve a hook where they can interrogate each of the changed nodes and perform additional logic prior to the actual persisting of the changes. Note that implementations are free to make additional modifications to the supplied nodes, and even create additional nodes or change persistent but unchanged nodes, as long as these operations are done within the same calling thread.
