  org.exoplatform.services.jcr.ext.registry.Registry
      org.exoplatform.services.jcr.ext.registry.RegistryService

All Implemented Interfaces:

org.picocontainer.Startable

public class RegistryService
extends Registry
implements org.picocontainer.Startable

Created by The eXo Platform SAS
Centralized collector for JCR based entities (services, apps, users) It contains info about the whole system, i.e. for all repositories used by system. All operations performed in context of "current" repository, i.e. RepositoryService.getCurrentRepository() Each repository has own Registry storage which is placed in workspace configured in "locations" entry like: locations registry locations The implementation hides storage details from end user
