项目用到Tess4J，涉及JNA，请问如何取得IntByReference类型变量获取到的C++数组

用到Tesseract开源项目来做文字简单的识别，查看所需要的函数的C++源码是这样的：

 /** Returns an array of all word confidences, terminated by -1. */
int* TessBaseAPI::AllWordConfidences() {
  if (tesseract_ == NULL ||
      (!recognition_done_ && Recognize(NULL) < 0))
    return NULL;
  int n_word = 0;
  PAGE_RES_IT res_it(page_res_);
  for (res_it.restart_page(); res_it.word() != NULL; res_it.forward())
    n_word++;

  int* conf = new int[n_word+1];
  n_word = 0;
  for (res_it.restart_page(); res_it.word() != NULL; res_it.forward()) {
    WERD_RES *word = res_it.word();
    WERD_CHOICE* choice = word->best_choice;
    int w_conf = static_cast<int>(100 + 5 * choice->certainty());
                 // This is the eq for converting Tesseract confidence to 1..100
    if (w_conf < 0) w_conf = 0;
    if (w_conf > 100) w_conf = 100;
    conf[n_word++] = w_conf;
  }
  conf[n_word] = -1;
  return conf;
}

而其java提供的接口函数是：

 IntByReference TessBaseAPIAllWordConfidences(TessBaseAPI handle);

涉及到的JNA是com.sun.jna.ptr.IntByReference，现在需要获取IntByReference变量的所有值，使用getValue方法只能获取到一个数。求做过相关内容的帮忙指点一下啦！
