## Implementation

    bool isFull() {

      try {
        var err = documentSDK.id3DocumentAuthenticator_IsFull(_pHandle.value, pResult);
        if (err != DocumentError.success.value) {
          throw DocumentException(err);
        }
        final vResult = pResult.value;
        return vResult;
      } finally {
        calloc.free(pResult);
      }
    }
