Examples of org.jahia.services.content.JCRSessionWrapper

org.jahia.services.content.JCRSessionWrapper
Jahia specific wrapper around javax.jcr.Session to be able to inject Jahia specific actions and to manage sessions to multiple repository providers in the backend.
Jahia services should use this wrapper rather than the original session interface to ensure that we manipulate wrapped nodes and not the ones from the underlying implementation. @author toto
