Detailed Description

The BehaviorContext struct contains shared resources that are common between all instances of Behaviors that inherit from moveit_studio::behaviors::SharedResourcesNode.

The BehaviorContext struct won't load a robot model by default. This is to avoid the cost of loading the robot model when it's not actually needed (e.g. tests), or needing to consume a timeout waiting for the model to be available. If a robot model is needed (e.g. when running on an actual robot), set load_robot_model=true when constructing the BehaviorContext. If load_robot_model=true and the robot model fails to load, the BehaviorContext will throw an exception and the program will terminate.

Member Data Documentation

callback_group_mutually_exclusive

const std::shared_ptr<rclcpp::CallbackGroup> moveit_studio::behaviors::BehaviorContext::callback_group_mutually_exclusive

A const shared pointer mutually-exclusive callback group.

Marked const to prevent Behaviors that can access BehaviorContext from changing it.

logger

const std::unique_ptr<moveit_studio::behavior::LoggerBase> moveit_studio::behaviors::BehaviorContext::logger

A const unique pointer to a logger for reporting messages to the UI.

Marked const to prevent Behaviors that can access BehaviorContext from changing it.

node

const std::shared_ptr<rclcpp::Node> moveit_studio::behaviors::BehaviorContext::node

A const shared pointer to a RCLCPP Node. This points to an instance of a Node provided when constructing the BehaviorContext.

Marked const to prevent Behaviors that can access BehaviorContext from changing it.

reentrant_callback_group

const std::shared_ptr<rclcpp::CallbackGroup> moveit_studio::behaviors::BehaviorContext::reentrant_callback_group

A const shared pointer reentrant callback group.

Marked const to prevent Behaviors that can access BehaviorContext from changing it.

robot_model

moveit::core::RobotModelPtr moveit_studio::behaviors::BehaviorContext::robot_model

The robot model, may be nullptr if the BehaviorContext was created with load_robot_model=false.

if load_robot_model=true, this is guaranteed to be a valid pointer.

transform_broadcaster

tf2_ros::TransformBroadcaster moveit_studio::behaviors::BehaviorContext::transform_broadcaster

transform_buffer

tf2_ros::Buffer moveit_studio::behaviors::BehaviorContext::transform_buffer

Transform buffer, listener, and broadcaster to interface with TF.

transform_listener

tf2_ros::TransformListener moveit_studio::behaviors::BehaviorContext::transform_listener
