  namespace Poco {
  
  class Foundation_API RefCountedObject
   A base class for objects that employ
 reference counting based garbage collection.
 Reference-counted objects inhibit construction
 by copying and assignment.
{
public:
        RefCountedObject();
 Creates the RefCountedObject.
 The initial reference count is one.
          void duplicate() const;
   Increments the object's reference count.
                
        void release() const;
 Decrements the object's reference count
 and deletes the object if the count
 reaches zero.
                
        int referenceCount() const;
 Returns the reference count.
  protected:
          virtual ~RefCountedObject();
   Destroys the RefCountedObject.
