interface FieldClassifier

Summary

FieldClassifier extends the base Detector contract. detect(field) attempts to classify the field and returns null (or a result with type "unknown") to pass control to the next classifier in the pipeline. Optionally, a classifier may implement detectAsync for strategies that require async I/O (e.g. Chrome Language AI). runAsync in DetectionPipeline will prefer detectAsync when present.

Source Code

export interface FieldClassifier extends Detector<
  FormField,
  ClassifierResult | null
> {
  readonly name: DetectionMethod;
  /** Optional async variant — used by DetectionPipeline.runAsync(). */
  detectAsync?(field: FormField): Promise<ClassifierResult | null>;
}
