Exception Class Referencefinal

Detailed Description

Lightweight exception type.

This class is a small convenience wrapper around std::exception that stores a formatted message assembled from any streamable arguments. In debug builds on Windows, if a debugger is attached, the message is also sent to the debugger output and a debug break is triggered to help you stop exactly at the throw site.
