Interface SlingRepository

  • All Superinterfaces:

    All Known Implementing Classes:
    AbstractSlingRepository2
    public interface SlingRepository
extends Repository
    The SlingRepository extends the standard JCR repository interface with two methods: getDefaultWorkspace() and loginAdministrative(String). This method ease the use of a JCR repository in a Sling application in that the default (or standard) workspace to use by the application may be configured and application bundles may use a simple method to get an administrative session instead of being required to provide their own configuration of administrative session details.

    Implementations of this interface will generally provide configurability of the default workspace name as well as the access details for the administrative session.

    Implementations of SlingRepository are expected to invoke any available implementations of the NamespaceMapper interface before returning any Session to callers. This includes the methods defined in the Repository interface.

    • Method Detail

      • getDefaultWorkspace

        java.lang.String getDefaultWorkspace()
        Returns the default workspace to use on login.
        Returns:
        null if the configured default workspace name is empty, SLING-256

      • loginAdministrative

        @Deprecated
Session loginAdministrative​(java.lang.String workspace)
                     throws LoginException,
                            RepositoryException
        Deprecated.
        as of 2.2 (bundle version 2.2.0) because of inherent security issues. Services requiring specific permissions should use the loginService(String, String) instead.
        Returns a session to the given workspace which has administrative powers.

        NOTE: This method is intended for use by infrastructure bundles to access the repository and provide general services. This method MUST not be used to handle client requests of whatever kinds. To handle client requests a regular authenticated session retrieved through Repository.login(javax.jcr.Credentials, String) or Session.impersonate(javax.jcr.Credentials) must be used.

        This method is deprecated. Services running in the Sling system should use the loginService(String serviceInfo, String workspace) method instead. Implementations of this method must throw javax.jcr.LoginException if they don't support it.

        Parameters:
        workspace - The name of the workspace to which to get an administrative session. If null the getDefaultWorkspace() default workspace is assumed.
        Returns:
        The administrative Session
        Throws:
        LoginException - If this method is not supported or is disabled by the implementation.
        RepositoryException - If an error occurs creating the administrative session

      • loginService

        Session loginService​(java.lang.String subServiceName,
                     java.lang.String workspace)
              throws LoginException,
                     RepositoryException
        Returns a session to the given workspace with privileges assigned to the service provided by the calling bundle. The subServiceName argument can be used to further specialize the service account to be used.
        Parameters:
        subServiceName - Optional Subservice Name to specialize account selection for the service. This may be null.
        workspace - The name of the workspace to which to get an administrative session. If null the getDefaultWorkspace() default workspace is assumed.
        Returns:
        A Session with appropriate permissions to execute the service.
        Throws:
        LoginException - If there is no service account defined for the calling bundle or the defined service account does not exist.
        RepositoryException - if an error occurs.
        Since:
        2.2 (bundle version 2.2.0) to replace loginAdministrative(String)

      • impersonateFromService

        Session impersonateFromService​(java.lang.String subServiceName,
                               Credentials credentials,
                               java.lang.String workspaceName)
                        throws LoginException,
                               RepositoryException
        Impersonates the service session provided by the calling bundle (and further specialized by subServiceName) to a new session in accordance with the specified (new) Credentials. The nature of the Credentials is an implementation detail which may allow relaxed credentials requirements (perhaps including a user ID but no password, for example).

        The impersonation will fail with LoginException if the service session is not allowed to impersonate the subject associated with the target session or if the specified Credentials credentials are not valid.

        The new, impersonated Session is tied to a new Workspace instance with the specified workspaceName or to the default workspace if the workspaceName is null.
        Parameters:
        subServiceName - Optional sub-service name to specialize account selection for the service. This may be null.
        credentials - A valid non-null Credentials object
        workspaceName - The name of the workspace to which to get an administrative session. If null the getDefaultWorkspace() default workspace is assumed.
        Returns:
        a new Session object
        Throws:
        LoginException - If the current session does not have sufficient access to perform the operation.
        RepositoryException - If another error occurs.
