Interface IFormulaEvaluator

  • All Known Implementing Classes:
    AbstractFormulaEvaluator
    public interface IFormulaEvaluator
    Evaluates the formulas of a product component or product component generation. This interface only provides methods to get the configured product component generation and to evaluate already configured formulas. The code of the formulas is set while creating the evaluator by an IFormulaEvaluatorFactory.
