A library cache profile response is the response to a library cache profile request. It contains the set of library names originally included in the request message and additionally a bit vector stating which of them are available in the respective task manager's local cache.




  @Override
  public LibraryCacheProfileResponse getLibraryCacheProfile(LibraryCacheProfileRequest request) throws IOException {


    LibraryCacheProfileResponse response = new LibraryCacheProfileResponse(request);
    String[] requiredLibraries = request.getRequiredLibraries();


    for (int i = 0; i < requiredLibraries.length; i++) {
      if (LibraryCacheManager.contains(requiredLibraries[i]) == null) {
        response.setCached(i, false);
      } else {
        response.setCached(i, true);
      }
    }


    return response;
  }
