Detailed Description

template<typename T>
class madara::utility::Refcounter< T >

This template class provides transparent reference counting of its template parameter T.

This differs from ScopedArray in the type of memory it is meant to manage. Refcounter manages single object instances. ScopedArray manages an array of instances,

This class can be used to automate the implementation of the Bridge pattern in C++.
