Exception

Description

The class Exception (see Figure C-4) is descended from std::exception. It contains a message describing the assertion failure and a SourceLine giving its location.

Exception contains a nested class named Exception::Type. The Type value represents the named Exception type, allowing runtime Exception type identification. For the base Exception class, the Type is CppUnit::Exception.

Exception belongs to the namespace CppUnit. It is declared in Exception.h and implemented in Exception.cpp.
