nested_exception Class

The class describes an exception for use with multiple inheritance. It captures the currently handled exception and stores it for later use.

Syntax

class nested_exception {
    public:
        nested_exception();
        nested_exception(const nested_exception&) = default;
        virtual ~nested_exception() = default; // access functions
};
