Detailed Description

<<reference-type>> This class provides an non-template holder for representing a Topic of any type

This class is useful for code that uses Topics of different types. It provides access to type-independent Topic functions.

An AnyTopic is always created from a typed Topic, increasing its reference count. The member function get() allows getting the typed Topic back.
