h5.archive_basic_layer.HDFArchiveGroupBasicLayer

class h5.archive_basic_layer.HDFArchiveGroupBasicLayer(parent, subpath)[source]

Low-level group operations backing HDFArchiveGroup.

Wraps a single HDF5 group handle from the compiled h5._h5py extension and exposes the primitive operations (querying, reading/writing datasets and attributes, creating groups and soft links) that the high-level dict-like interface is built on.

This is the base class of HDFArchiveGroup. Users should not instantiate it directly.

Parameters:

parentHDFArchive or HDFArchiveGroup: Object whose _group handle and options are used as the base.
subpathstr: Name of the subgroup to open; if empty, parent’s group is reused.

Methods

`create_group`(key)	Create a new empty subgroup.
`create_softlink`(target_key, key[, ...])	Create an HDF5 soft link `key` pointing at `target_key`.
`is_data`(p)	Return whether `p` names a dataset (leaf) of this group.
`is_group`(p)	Return whether `p` names a subgroup of this group.
`keys`()	Return the names of the entries in this group.
`write_attr`(key, val)	Write an HDF5 attribute on this group.
