Fully qualified name: isaacsim::ros2::bridge::Ros2ClockMessage

class Ros2ClockMessage : public isaacsim::ros2::bridge::Ros2Message

Class implementing a rosgraph_msgs/msg/Clock message.

Provides functionality to read and write ROS 2 Clock messages that contain simulation time information.

Subclassed by isaacsim::ros2::bridge::Ros2ClockMessageImpl

Public Functions

virtual void readData(double &timeStamp) = 0

Read the message field values.

Extracts the timestamp value from a ROS 2 Clock message.

Parameters:

timeStamp – [out] Time (seconds).

virtual void writeData(double timeStamp) = 0

Write the message field values from the given arguments.

Sets the timestamp value in a ROS 2 Clock message.

Parameters:

timeStamp – [in] Time (seconds).

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.

virtual const void *getTypeSupportHandle() = 0

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.

Protected Attributes

void *m_msg = nullptr
