Detailed Description

template<typename M>
class ros::MessageEvent< M >

Event type for subscriptions, const ros::MessageEvent<M const>& can be used in your callback instead of const boost::shared_ptr<M const>&.

Useful if you need to retrieve meta-data about the message, such as the full connection header, or the publisher's node name
