        public static ZipFile open​(String fileName)
        Open npz data file
        参数:
        fileName - The file name
        返回:
        ZipFile object

        Returns the names of the entries of the given NPZ file.
        参数:
        fileName - a NPZ file name
        返回:
        the names of the entries of the NPZ file

      • entries

        public static List<String> entries​(File npz)
        Returns the names of the entries of the given NPZ file.
        参数:
        npz - a NPZ file
        返回:
        the names of the entries of the NPZ file

        Read an array from an entry of a NPZ file.
        参数:
        npz - the NPZ file
        entry - the name of the entry in which the array is stored
        返回:
        the array of the entry

      • use

        public static void use​(File npz,
                       Consumer<ZipFile> fn)
        Open the given file as an NPZ file. This function is useful when you want to do multiple things with a NPZ file, e.g. 
        
 Npz.use(file, npz -> {
   for (var entry : Npz.entries(npz)) {
     var array = Npz.read(npz, entry);
     // ...
   }
 });
        参数:
        npz - the NPZ file
        fn - a consumer function of the opened NPZ file
