Detailed Description

Manages an subscription callback on a specific topic.

A Subscriber should always be created through a call to NodeHandle::subscribe(), or copied from one that was. Once all copies of a specific Subscriber go out of scope, the subscription callback associated with that handle will stop being called. Once all Subscriber for a given topic go out of scope the topic will be unsubscribed.

void ros::Subscriber::shutdown ( )

Unsubscribe the callback associated with this Subscriber.

This method usually does not need to be explicitly called, as automatic shutdown happens when all copies of this Subscriber go out of scope

This method overrides the automatic reference counted unsubscribe, and immediately unsubscribes the callback associated with this Subscriber
