HDF5 Group Interface: HDF5 Group Interface

Description

The Group interface functions create and manipulate groups of objects in an HDF5 file.

Usage

H5Gcreate      (h5loc, name)
H5Gcreate_anon (h5loc)
H5Gopen        (h5loc, name)
H5Gclose       (h5group)
H5Gget_info    (h5loc)
H5Gget_info_by_idx  (h5loc, n, group_name = ".",  index_type = h5default("H5_INDEX"), 
		       order = h5default("H5_ITER"))
H5Gget_info_by_name (h5loc, group_name)

Arguments

h5loc

An object of class H5IdComponent representing a H5 location identifier (file or group). See H5Fcreate, H5Fopen, H5Gcreate, H5Gopen to create an object of this kind.

name

Name of the group.

h5group

An object of class H5IdComponent representing a H5 group identifier. See H5Gcreate, H5Gopen to create an object of this kind.

Position in the index of the group for which information is retrieved (Counting is 1-based).

group_name

An additional group name specifying the group for which information is sought. It is interpreted relative to h5loc.

index_type

See h5const("H5_INDEX") for possible arguments.

order

See h5const("H5_ITER") for possible arguments.

Value

H5Gcreate, H5Gcreate_anon, and H5Gopen return an object of class H5IdComponent representing a H5 group identifier.H5Gget_info, H5Gget_info_by_idx, and H5Gget_info_by_name return a list with the group information.The other functions return the standard return value from their respective C-functions.

Details

Interface to the HDF5 C-library libhdf5. See http://www.hdfgroup.org/HDF5/doc/RM/RM_H5G.html for further details.
