`create(parent, body=None, languageCode=None, x__xgafv=None)`

    Creates an TransitionRouteGroup in the specified flow. Note: You should always train a flow prior to sending it queries. See the [training documentation](https://cloud.google.com/dialogflow/cx/docs/concept/training).

    Args:
      parent: string, Required. The flow to create an TransitionRouteGroup for. Format: `projects//locations//agents//flows/` or `projects//locations//agents/` for agent-level groups. (required)
      body: object, The request body.
        The object takes the form of:

When a specified transition is matched, the following actions are taken in order: * If there is a `trigger_fulfillment` associated with the transition, it will be called. * If there is a `target_page` associated with the transition, the session will transition into the specified page. * If there is a `target_flow` associated with the transition, the session will transition into the specified flow.
          "condition": "A String", # The condition to evaluate against form parameters or session parameters. See the [conditions reference](https://cloud.google.com/dialogflow/cx/docs/reference/condition). At least one of `intent` or `condition` must be specified.

`delete(name, force=None, x__xgafv=None)`

    Deletes the specified TransitionRouteGroup. Note: You should always train a flow prior to sending it queries. See the [training documentation](https://cloud.google.com/dialogflow/cx/docs/concept/training).

    Args:

      force: boolean, This field has no effect for transition route group that no page is using. If the transition route group is referenced by any page: * If `force` is set to false, an error will be returned with message indicating pages that reference the transition route group. * If `force` is set to true, Dialogflow will remove the transition route group, as well as any reference to it.

    Returns:
      An object of the form:

        { # A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); }
