getIdList method

List<int> getIdList()

Gets the list of IDs in the list.

return The list of IDs in the list. throws FaceException An error has occurred during Face Library execution.

Implementation

List<int> getIdList() {
  Pointer<Int> pIds = nullptr;
  Pointer<Int> pIdsSize = calloc();
  pIdsSize[0] = -1;
  try {
    var err = faceSDK.id3TrackedFaceList_GetIdList(_pHandle.value, pIds, pIdsSize);
    if (err == FaceError.insufficientBuffer.value) {
      pIds = calloc.allocate(pIdsSize.value);
      err = faceSDK.id3TrackedFaceList_GetIdList(_pHandle.value, pIds, pIdsSize);
    }
    if (err != FaceError.success.value) {
      throw FaceException(err);
    }
    final vIds = Int32List.fromList(pIds.cast<Int32>().asTypedList(pIdsSize.value));
    return vIds;
  } finally {
    calloc.free(pIds);
    calloc.free(pIdsSize);
  }
