    • registerBinaryImplementers

      public void registerBinaryImplementers(ClassLoader cl)
      Method allows registering additional class loaders, to load classes, implementing binary expressions. This is especially necessary for expression implementations, coming from plugins (otherwise these implementation classes will not be found - since they are in a separate class loader - plugin class loader).
      Parameters:
      cl - class loader, supplying additional classes, implementing expressions

    • registerEvaluator

      Parameters:
      language - language identifier.
      evaluator - an evaluator object.

    • unregisterEvaluator

      public void unregisterEvaluator(String language)
