template<typename NodeT >

void nav2_smac_planner::SmacPlannerHybridT< NodeT >::updateParametersCallback ( const std::vector< rclcpp::Parameter > & parameters )

protected

Apply parameter updates after validation This callback is executed when parameters have been successfully updated. It updates the internal configuration of the node with the new parameter values.

Parameters

parameters List of parameters that have been updated.

◆ validateParameterUpdatesCallback()

template<typename NodeT >

rcl_interfaces::msg::SetParametersResult nav2_smac_planner::SmacPlannerHybridT< NodeT >::validateParameterUpdatesCallback ( const std::vector< rclcpp::Parameter > & parameters )

protected

Validate incoming parameter updates before applying them. This callback is triggered when one or more parameters are about to be updated. It checks the validity of parameter values and rejects updates that would lead to invalid or inconsistent configurations.

Parameters

parameters List of parameters that are being updated.

Returns: rcl_interfaces::msg::SetParametersResult Result indicating whether the update is accepted.
