Constructor & Destructor Documentation

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.

const std::string &  description

Usually, Handler is capable to recover from errors by itself. That means, there's no need to restart manually. Instead, Handler will perform all necessary recovering by itself.
