NAME

       zipios::ReferenceCount< Type > - ReferenceCount is useful to ensure proper handling of the
       reference count for (objects of) classes handled through a SimpleSmartPointer.

SYNOPSIS

       #include <simplesmartptr.h>

   Public Member Functions
       ReferenceCount ()
           Constructor intializes count to zero.
       ReferenceCount (const ReferenceCount &src)
           Copy-constructor intializes count to zero.
       const ReferenceCount & operator= (const ReferenceCount &src)
           The assignment operator doesn't copy the reference count, it leaves it unchanged.

   Friends
       class SimpleSmartPointer< Type >
           SimpleSmartPointer needs to be a friend to invoke the private ref() and unref()
           methods.
       class SimpleSmartPointer< const Type >
       class FileEntry
           Type also needs to be a friend to invoke the private ref() and unref() methods, in
           case Type doesn't want to inherit ReferenceCount and thus needs to invoke ref() and
           unref() through forwarding member functions.

Detailed Description

   template<class Type>
       class zipios::ReferenceCount< Type >" ReferenceCount is useful to ensure proper handling
       of the reference count for (objects of) classes handled through a SimpleSmartPointer.

       Subclassing ReferenceCount is all a class needs to become ready for being handled by
       SimpleSmartPointer. Another way is to add a ReferenceCount member variable to a class and
       write two methods 'void ref() const' and 'unsigned int unref() const' that invoke the same
       methods in the ReferenceCount variable.
