Detailed Description

template<class Message, typename Enable = ::std::enable_if_t<::ros::message_traits::IsMessage<Message>::value>>
class cras::DiagnosedPubSub< Message, Enable >

Base for ROS publisher and subscriber with automatic message rate and delay diagnostics.

This class offers an option to configure the diagnostic task from a set of ROS parameters. The following parameters are read:

• rate/desired (double, Hz, no default): If set, this value will be used as the default of min/max rates.
• rate/min (double, Hz, default 0.0 or desired): Minimum acceptable rate.
• rate/max (double, Hz, default +inf or desired): Maximum acceptable rate.
• rate/tolerance (double, default 0.1): Tolerance of the min/max rate (0.0 means that the min/max rate limits are strict).
• rate/window_size (uint, default 5): Over how many diagnostics updates should the rate be computed.
• delay/min (double, s, default -1.0): Minimum acceptable delay (only computed for messages with a header).
• delay/max (double, s, default 5.0): Maximum acceptable delay (only computed for messages with a header).

Template Parameters

Message	Type of the published/subscribed message.
Enable	SFINAE only. Do not explicitly set.
