H5Node class

class H5Node(h5py_item=None)

Bases: object

Adapter over an h5py object to provide missing informations from h5py nodes, like internal node path and filename (which are not provided by h5py for soft and external links).

It also provides an abstraction to reach node type for mimicked h5py objects.

property h5py_object

Returns the internal h5py node.

Return type

h5py.File or h5py.Group or h5py.Dataset

property h5type

Returns the node type, as an H5Type.

Return type

H5Node

property ntype

Returns the node type, as an h5py class.

Return type

h5py.File, h5py.Group or h5py.Dataset

property basename

Returns the basename of this h5py node. It is the last identifier of the path.

Return type

str

property is_broken

Returns true if the node is a broken link.

Return type

bool

property local_name

Returns the path from the master file root to this node.

For links, this path is not equal to the h5py one.

Return type

str

property local_file

Returns the master file in which is this node.

For path containing external links, this file is not equal to the h5py one.

Return type

h5py.File

Raises

RuntimeException – If no file are found

property local_filename

Returns the filename from the master file of this node.

For path containing external links, this path is not equal to the filename provided by h5py.

Return type

str

Raises

RuntimeException – If no file are found

property local_basename

Returns the basename from the master file root to this node.

For path containing links, this basename can be different than the basename provided by h5py.

Return type

str

property physical_file

Returns the physical file in which is this node.

New in version 0.6.

Return type

h5py.File

Raises

RuntimeError – If no file are found

property physical_name

Returns the path from the location this h5py node is physically stored.

For broken links, this filename can be different from the filename provided by h5py.

Return type

str

property physical_filename

Returns the filename from the location this h5py node is physically stored.

For broken links, this filename can be different from the filename provided by h5py.

Return type

str

property physical_basename

Returns the basename from the location this h5py node is physically stored.

For broken links, this basename can be different from the basename provided by h5py.

Return type

str

property data_url

Returns a silx.io.url.DataUrl object identify this node in the file system.

Return type

DataUrl

property url

Returns an URL object identifying this node in the file system.

This URL can be used in different ways.

# Parsing the URL
import silx.io.url
dataurl = silx.io.url.DataUrl(item.url)
# dataurl provides access to URL fields

# Open a numpy array
import silx.io
dataset = silx.io.get_data(item.url)

# Open an hdf5 object (URL targetting a file or a group)
import silx.io
with silx.io.open(item.url) as h5:
    ...your stuff...

Return type

str
