  • Method Details

    • action

      ActionResponse action(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.
      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.
      UnsupportedOperationException - If this connection does not support action requests.
      IllegalStateException - If this connection has already been closed, i.e. if isClosed() == true.

    • actionAsync

      Promise<ActionResponse,ResourceException> actionAsync(Context context, ActionRequest request)
      Asynchronously performs an action against a specific resource, or set of resources. Bulk updates are an example of an action request.
      Parameters:
      context - The request context, such as associated principal.
      request - The action request.
      Returns:
      A future representing the result of the request.
      Throws:
      UnsupportedOperationException - If this connection does not support action requests.
      IllegalStateException - If this connection has already been closed, i.e. if isClosed() == true.

    • close

      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.
