Fully qualified name: isaacsim::ros2::bridge::Ros2SemanticLabelMessageImpl

class Ros2SemanticLabelMessageImpl : public isaacsim::ros2::bridge::Ros2SemanticLabelMessage, private isaacsim::ros2::bridge::Ros2MessageInterfaceImpl

Handles the creation and manipulation of std_msgs/msg/String messages used for semantic labeling in perception tasks.

Public Functions

Ros2SemanticLabelMessageImpl()

virtual ~Ros2SemanticLabelMessageImpl()

virtual const void *getTypeSupportHandle()

Gets the type support handle for the message.

Returns a pointer to the ROS IDL message type support data structure. The actual type depends on the message category:

• Topic: rosidl_message_type_support_t

• Service: rosidl_service_type_support_t

• Action: rosidl_action_type_support_t

Returns:

Pointer to the type support structure or nullptr.

virtual void writeData(const std::string &data)

Sets the semantic label data.

Parameters:

data – [in] String containing the semantic label

inline void *getPtr()

Retrieves the message pointer.

Returns the pointer to the underlying ROS 2 message if it has been properly created and initialized.

Note

This method does not perform type checking - the caller is responsible for proper casting to the appropriate message type.

Returns:

Pointer to the message or nullptr if not initialized.
