Interface IExpressionEvaluator

An evaluator for RDF expressions.

interface IExpressionEvaluator {
    context: IActionContext;
    evaluate: (mapping: Bindings) => Promise<Term>;
    evaluateAsEBV: (mapping: Bindings) => Promise<boolean>;
    evaluateAsEvaluatorExpression: (
        mapping: Bindings,
    ) => Promise<TermExpression>;
    evaluatorExpressionEvaluation: (
        expr: Expression,
        mapping: Bindings,
    ) => Promise<TermExpression>;
}

Properties

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

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

- (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.

- (mapping: Bindings): Promise<boolean>
- Parameters
  - mapping: Bindings
    the RDF bindings to evaluate against.
  Returns Promise<boolean>

evaluateAsEvaluatorExpression: (mapping: Bindings) => Promise<TermExpression>

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