Detailed Description

Exception class for error handling in GENFIT (provides storage for diagnostic information)

Author

Christian Höppner (Technische Universität München, original author)

Sebastian Neubert (Technische Universität München, original author)

This is the class that is used for all error handling in GENFIT. It is a utility class that allows to store numbers and matrices together with an error string. The exception class can then be thrown when an error is detected and the C++ exception handling facilities can be used to catch and process the exception.
