10:07 Changeset [8833] by sforsten


  • removed combo box in TimeframeCorrelationView and added a textbox instead
  • caches are directly in (Timeframe-)FeatureCorrelationView
  • caches use Tuple<> instead of nested dictionaries
  • a control EnhancedStringConvertibleMatrix inherits from StringConvertibleMatrixView to reduce code duplication
  • add interface IDependencyCalculator to several calculators
  • fixed bug: a previous started calculation is cancelled, if a new calculation shall be started and the values are already in the cache
  • fixed bug: if the content is changed, the calculation is cancelled

HeatMap is still used for the dependency representation, because a class is needed which implements IStringConvertibleMatrix and it has a maximum and minimum value.

  • Added a parser for independent scenarios (using the model of the optimization backend)
  • Optimization scenario sample can be found in mappings folder of the web project.
  • Added IScenarioMapper interface which provides functionality to map from the optimization data model to a backend model (e.g. Heuristic Lab data model)
  • Implementations of IScenarioMapper have to be provided as C# code (strings) which will be compiled by using a CSharpCodeProvider. Once compiled, the implementations of the IScenarioMapper are being cached within the platform for further usage.
  • Fixed a bug in web template DecimalMatrix (using i instead of j)
  • Added missing thumprint of localhost certificate to the optimization web project (ServiceConfiguration.Local.cscfg / ServiceConfiguration.Cloud.cscfg)
