• To provide inputs and results to be presented to the user on a tab when the user is browsing the model and looking at various tabs (of the type simple or dashboard), or looking at details of a tree node (on the tab of the type filtertree).

• When a logic from another module (e.g. Quotes) needs to get data from a model, it can call the model’s evaluation (and pass parameters to it) which will call the evaluation logic to provide the information from the model.

• When Product Recommendation is configured for Quotes, it can use the Model’s Evaluation (and thus the evaluation logic) to retrieve the list of recommended products.

The evaluation logic characteristics:

...

• Logic Nature: model_evaluation

• Execution Types:

  • Syntax Check – Defines the input fields of the logic. In case of tabs, they will be rendered on the page, but in case of evaluation, it will be used to receive the parameters passed from other logics.

  • Standard – Calculates and provides the results.

• Information provided to the logic:

  • Syntax Check:

    • Binding variables:

      • model (see ModelEvaluationFormulaContext) includes Model Table, inputs from previous steps and outputs from previous calculations.

  • Standard:

    • Binding variables:

      • model (see ModelEvaluationFormulaContext) includes Model Table, inputs from previous steps and outputs from previous calculations.

      • input (Map) – When used on a tab, it contains values of all inputs provided by the user in the input fields of the current tab. When used in evaluation, it contains the parameters values passed to the logic.

• Expected logic execution outcome:

  • Syntax Check:

    • Input field definitions placed in the logic context

  • Standard:

    • in case of usage by Product Recommendation feature on Quotes:

      • one element must return result of type List<ItemRecommendation>

    • in other cases (e.g. Tabs evaluation, etc)

      • Results and their formatting are provided via the output of the visible (with DisplayMode set) logic elements.

        • Critical Alert – When used on a tab, it will block the Continue button.

      • The result value can be of almost any type:

        • Simple: String, BigDecimal, Map, List, …

        • Complex: Chart, ResultMatrix, Controller, …
