Detailed Description

Exception class for assertions. Besides the information already present in ExceptionBase, this class features more information about the assertion which failed. The ouput operator (<<) can display this information.

The typical usage of this class is to throw an exception if an assertion has failed. This can be done by

conceptsAssert(1 == 0, Assertion());

These exceptions are not always present, since the macro conceptsAssert is switched off in production code. If you want to have exceptions which are always present, have a look at ExceptionBase and conceptsException.
