This *severely* limits the usefulness of this function.\n *\n * ### Example:\n *\n * ```typescript\n * class HTTP {}\n * class Database {}\n *\n * // commenting out the decorator because the `@` symbol is spoiling\n * // jsDoc rendering in vscode\n * // @Injectable()\n * class PersonService {\n *   constructor(\n *     private http: HTTP,\n *     private database: Database,\n *   ) {}\n * }\n *\n * // @Injectable()\n * class OrganizationService {\n *   constructor(\n *     private http: HTTP,\n *     private personService: PersonService,\n *   ) {}\n * }\n *\n * const injector = ReflectiveInjector.resolveAndCreate(\n *   resolveDependencies(OrganizationService)\n * );\n *\n * const organizationService = injector.get(OrganizationService);\n * ```\n */\nexport function resolveDependencies(...inputs: Constructor[]) {\n  const deps = new Set<Constructor>();\n\n  function resolver(klass: Constructor) {\n    if (deps.has(klass)) return;\n\n    deps.add(klass);\n\n    // resolve all dependencies of the provided class and run the `resolver()` function\n    // on their constructor functions.\n    ReflectiveInjector.resolve([klass])\n      .reduce((a, x: ResolvedReflectiveProvider) => a.concat(x.resolvedFactories), [] as ResolvedReflectiveFactory[])\n      .reduce((a, r: ResolvedReflectiveFactory) => a.concat(r.dependencies), [] as ReflectiveDependency[])\n      .forEach((d) => resolver(d.key.token as Constructor));\n  }\n\n  for (const input of inputs) {\n    resolver(input);\n  }\n\n  return Array.from(deps);\n}\n"]}
