Detailed Description

template<typename ActionT>
class rclcpp_action::ClientGoalHandle< ActionT >

Class for interacting with goals sent from action clients.

Use this class to check the status of a goal as well as get the result.

This class is not meant to be created by a user, instead it is created when a goal has been accepted. A Client will create an instance and return it to the user (via a future) after calling Client::async_send_goal.
