    public class SilverpeasRepository
extends Object
implements javax.jcr.Repository
    Implementation of the Repository in Silverpeas. The SilverpeasRepository objects are created by a SilverpeasRepositoryFactory instance.

    It is in fact a wrapper of the actual Repository object used to access the JCR with the goal to wrap the login/logout operations in order to implement a reentrant JCR session. Indeed, in Silverpeas several accesses to the JCR can be performed within a single flow of treatment (and hence a single thread) and these accesses can be asked by independent services. As these services don't know what it was done out of their own scope, they cannot know whether a session has been already opened with the JCR and hence ask for their own use to open a session. In order to avoid inter-blocking and interleaving session, a mechanism of reentrant session is implemented in Silverpeas with the aim to reuse an opened session within the same single thread.

    So, when a call to a login method is performed, the first thing the method does is to check a session is already opened. In this case, this session is just returned, otherwise a true login is performed driving to the creation and the opening of a new session to the workspace of the repository (in Silverpeas, there is only one workspace).
