| HDF5File | 6 | |
| HDF5Ptr | A internal pointer in a hdf5 binary data file. | 3 |
| HDF5Reader | 这个reader只会读取一个HDF5Reader.datasetName的数据，如果需要读取其他的dataset的话， 则会需要创建多个HDF5Reader对象来进行数据的读取操作 这个对象相当于文件系统之中的一个文件或者文件夹 | 5 |
| HDF5Sparse | 稀疏感知的 HDF5 读取辅助集合。所有方法都避免将整个数据集一次性解压到内存： 分块数据集按 chunk 流式枚举，COO 三元组直接构造 SparseMatrix。 | 4 |
