Changeset 418 for trunk/sources/HeuristicLab.CEDMA.Core/DatabaseOperatorLibrary.cs

Timestamp:

Message:

worked on #211 (Full operator-graphs are stored multiple times in the database even though most of it is static anyway)

• added class OperatorLink that allows to create CombinedOperators in the DatabaseOperatorLibrary which use other operators from the library (not via a copy but via a link)

File:

• trunk/sources/HeuristicLab.CEDMA.Core/DatabaseOperatorLibrary.cs (modified) (5 diffs)
