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): 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): 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>)
