Implementation

APIObject resolveUri(Uri uri) {
  final segments = uri.pathSegments;
  if (segments.length != 3) {
    throw new ArgumentError(
        "Invalid reference URI. Must be a path URI of the form: '/components/<type>/<name>'");
  }

  if (segments.first != "components") {
    throw new ArgumentError(
        "Invalid reference URI: does not begin with /components/");
  }

  var namedMap = null;
  switch (segments[1]) {
    case "schemas":
      namedMap = schemas;

    throw new ArgumentError(
        "Invalid reference URI: component type '${segments[1]}' does not exist.");
