Template Parameters:

T – the ROS2 message type to collect

Public Functions

TopicStatisticsCollector() = default

virtual ~TopicStatisticsCollector() = default

virtual void OnMessageReceived(const T &received_message, const rcl_time_point_value_t now_nanoseconds) = 0

Handle receiving a single message of type T.

Parameters:

• received_message – T the ROS2 message type to collect

• now_nanoseconds – nanoseconds the time the message was received. Any metrics using this time assumes the following 1). the time provided is strictly monotonic 2). the time provided uses the same source as time obtained from the message header.
