Constructor & Destructor Documentation

~ErrorListener()

virtual ~ErrorListener ( )

inlineprotectedvirtual

Class provides an interface for handling errors in subscriptions. It doesn't provide an interface for instance deletion. However, since C++ doesn't have pure interface concept, destructor will be generated anyway. We can only control proper use of it. For this reason we hide from public use and make it available for descendants.
