Detailed Description

template<class M>
class message_filters::SimpleFilter< M >

Convenience base-class for simple filters which output a single message.

SimpleFilter provides some of the tricky callback registering functionality, so that simple filters do not have to duplicate it. It also provides getName()/setName() for debugging purposes.
