org.wso2.carbon.registry.core.session.UserRegistry
Maintains information required for particular user. When registry functionality is invoked through this objects of this class, user's information is passes along the thread of invocation. Therefore, all the actions are recorded against that user's name and all authorizations are checked using that user's realm. Note that, although this class maintains user details, it does not perform any authorization. Underlying registry or other entities in the thread of invocation should perform authorizations as needed using the realm given by this class. In addition to associating user with the registry, this will be used to get a chrooted registry, as the new constructors accept chroot as the last parameter.
