source: branches/Operator Architecture Refactoring/HeuristicLab.Logging/Logger.cs @ 606

Last change on this file since 606 was 283, checked in by gkronber, 16 years ago
  • added a more generic logging operator that allows to specify which variable to read from the sub-scopes and log.
  • changed LogView to display entries by calling .ToString() instead of the hard-coded cast to DoubleArrayData.
