Detailed Description

The LogMethod class.

This class allows the logging of the entering and leaving point of a method. Therefore an object of this class is created on the stack, which logs a message at the moment it is created and destroyed. In addition, it logs a message if there are any uncaught exceptions pending at the time the object is destroyed on the stack. This allows to identify methods which were terminated due to a thrown exception.
