Abstract class representing an action based BT node.
static BT::PortsList providedBasicPorts(BT::PortsList addition)
Any subclass of BtActionNode that accepts parameters must provide a providedPorts method and call pro...
A nav2_behavior_tree::BtActionNode class that wraps nav2_msgs::action::ComputeRoute.
BT::NodeStatus on_cancelled() override
Function to perform some user-defined operation upon cancellation of the action.
ComputeRouteAction(const std::string &xml_tag_name, const std::string &action_name, const BT::NodeConfiguration &conf)
A constructor for nav2_behavior_tree::ComputeRoute.
void halt() override
Override required by the a BT action. Cancel the action and set the path output.
void on_tick() override
Function to perform some user-defined operation on tick.
static BT::PortsList providedPorts()
Creates list of BT ports.
void resetPorts()
Reset output port values on failure.
BT::NodeStatus on_aborted() override
Function to perform some user-defined operation upon abortion of the action.
BT::NodeStatus on_success() override
Function to perform some user-defined operation upon successful completion of the action.
