How to use the @loopback/metadata.MetadataInspector.getAllParameterMetadata function in @loopback/metadata

let meta: Readonly[] = cache[method];
  if (meta) return meta;

  // Build the description
  const options: InspectionOptions = {};
  if (method === '') {
    if (shouldSkipBaseConstructorInjection(target)) {
      options.ownMetadataOnly = true;
    }
  } else if (Object.prototype.hasOwnProperty.call(target, method)) {
    // The method exists in the target, no injections on the super method
    // should be honored
    options.ownMetadataOnly = true;
  }
  meta =
    MetadataInspector.getAllParameterMetadata>(
      PARAMETERS_KEY,
      target,
      method,
      options,
    ) ?? [];

  // Cache the result
  cache[method] = meta;
  MetadataInspector.defineMetadata[]>>(
    METHODS_KEY,
    cache,
    target,
  );
  return meta;
}
