    Interface IExpressionEvaluator

    An evaluator for RDF expressions.

    interface IExpressionEvaluator {
        context: IActionContext;
        evaluate: (mapping: Bindings) => Promise<Term>;
        evaluateAsEBV: (mapping: Bindings) => Promise<boolean>;

    Properties

    context: IActionContext
    evaluate: (mapping: Bindings) => Promise<Term>

    Evaluates the provided bindings in terms of the context the evaluator was created.

    Type Declaration

      • (mapping: Bindings): Promise<Term>

      • Parameters

        • mapping: Bindings

          the RDF bindings to evaluate against.

        Returns Promise<Term>

    evaluateAsEBV: (mapping: Bindings) => Promise<boolean>

    Evaluates the provided bindings in terms of the context the evaluator was created, returning the effective boolean value.

    Type Declaration

      • (mapping: Bindings): Promise<boolean>

      • Parameters

        • mapping: Bindings

          the RDF bindings to evaluate against.

        Returns Promise<boolean>

    evaluateAsEvaluatorExpression: (mapping: Bindings) => Promise<TermExpression>
    evaluateDirectly?: (
        expr: Expression,
        mapping: Bindings,
    ) => TermExpression | undefined

    Evaluate the given expression synchronously, which is possible for term or variable expressions.

    Type Declaration

    evaluatorExpressionEvaluation: (
        expr: Expression,
        mapping: Bindings,
    ) => Promise<TermExpression>
