Detailed Description

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

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

This differs from Refcounter in the members available and the deletion of memory. Refcounter deletes a single T memory location when the last instance of the pointer goes out of scope. ScopedArray deletes an array of T objects when the pointer goes out of scope.

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