    Directory implementation which simply delegates all function calls to an underlying Directory.

    • Constructor Detail

      • DelegatingDirectory

        public DelegatingDirectory​(Directory<ObjectType> directory)
        Wraps the given Directory such that all function calls against this DelegatingDirectory will be delegated to it.
        Parameters:
        directory - The directory to wrap.

    • Method Detail

      • getDelegateDirectory

        protected Directory<ObjectType> getDelegateDirectory()
        Returns the underlying Directory wrapped by this DelegatingDirectory.
        Returns:
        The Directory wrapped by this DelegatingDirectory.

      • get

        public ObjectType get​(String identifier)
               throws org.apache.guacamole.GuacamoleException
        Description copied from interface: Directory
        Returns the object having the given identifier. Note that changes to the object returned will not necessarily affect the object stored within the Directory. To update an object stored within an Directory such that future calls to get() will return the updated object, you must call update() on the object after modification.
        Specified by:
        get in interface Directory<ObjectType extends Identifiable>
        Parameters:
        identifier - The identifier to use when locating the object to return.
        Returns:
        The object having the given identifier, or null if no such object exists.
        Throws:
        org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the object, or if permission for retrieving the object is denied.

      • getAll

        public Collection<ObjectType> getAll​(Collection<String> identifiers)
                              throws org.apache.guacamole.GuacamoleException
        Description copied from interface: Directory
        Returns the objects having the given identifiers. Note that changes to any object returned will not necessarily affect the object stored within the Directory. To update an object stored within a Directory such that future calls to get() will return the updated object, you must call update() on the object after modification.
        Specified by:
        getAll in interface Directory<ObjectType extends Identifiable>
        Parameters:
        identifiers - The identifiers to use when locating the objects to return.
        Returns:
        The objects having the given identifiers. If any identifiers do not correspond to accessible objects, those identifiers will be ignored. If no objects correspond to any of the given identifiers, the returned collection will be empty.
        Throws:
        org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the objects, or if permission to retrieve the requested objects is denied.

      • getIdentifiers

        public Set<String> getIdentifiers()
                           throws org.apache.guacamole.GuacamoleException
        Description copied from interface: Directory
        Returns a Set containing all identifiers for all objects within this Directory.
        Specified by:
        getIdentifiers in interface Directory<ObjectType extends Identifiable>
        Returns:
        A Set of all identifiers.
        Throws:
        org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the identifiers.

        Parameters:
        object - The object to add.
