AException

Abstract AUI exception.

Header:	#include <AUI/Common/AException.h>
CMake:	aui_link(my_target PUBLIC aui::core)

Detailed Description

Unlike std::exception, AException is capable to capture stack traces and efficiently output them to std::ostream. Also exception nesting is possible (via causedBy()).
