      • action

        public ActionResponse action​(org.forgerock.services.context.Context context,
                             ActionRequest request)
                      throws ResourceException
        Performs an action against a specific resource, or set of resources. Bulk updates are an example of an action request.

        The default implementation is to delegate.

        Specified by:
        action in interface Connection
        Parameters:
        context - The request context, such as associated principal.
        request - The action request.
        Returns:
        A JSON object containing the result of the action, the content of which is specified by the action.
        Throws:
        ResourceException - If the action could not be performed.

      • actionAsync

        public Promise<ActionResponse,​ResourceException> actionAsync​(org.forgerock.services.context.Context context,

        Asynchronously performs an action against a specific resource, or set of resources. Bulk updates are an example of an action request.

        The default implementation is to delegate.

        Parameters:
        context - The request context, such as associated principal.
        request - The action request.
        Returns:
        A future representing the result of the request.

      • close

        public void close()
        Releases any resources associated with this connection. For physical connections to a server this will mean that the underlying socket is closed.

        Other connection implementations may behave differently. For example, a pooled connection will be released and returned to its connection pool.

        Calling close on a connection that is already closed has no effect.

        The default implementation is to delegate.
