nixio.hdf5.h5group module
- class nixio.hdf5.h5group.H5Group(parent, name, create=False)
Bases:
object
- copy(source, dest, name=None, cls=None, shallow=False, keep_id=True)
- create_dataset(name, shape, dtype, compression=False)
Creates a dataset object under the current group with a given name, shape, and type.
- Parameters
name – the name of the dataset
shape – tuple representing the shape of the dataset
dtype – the type of the data for this dataset (DataType)
compression – whether to compress the data (default: False)
- Returns
a new H5DataSet object
- classmethod create_from_h5obj(h5obj)
- create_link(target, name)
- delete(id_or_name, delete_if_empty=True)
Deletes the child HDF5 group that matches the given name or id.
- delete_all(eid)
Deletes all references to a given list of objects, identified by their entity_id, below the current object.
- find_children(filtr=None, limit=None)
- get_attr(name)
- get_by_id(id_)
- get_by_id_or_name(id_or_name)
- get_by_name(name)
- get_by_pos(pos)
- get_data(name)
Returns the data contained in the dataset identified by ‘name’, or an empty list if a dataset of that name does not exist in the Group.
- Parameters
name – The name of the dataset
- Returns
The data contained in the dataset as a numpy array or None
- get_dataset(name)
Returns a contained H5DataSet object.
- Parameters
name – name of the dataset
- Returns
H5DataSet object
- property group
- has_by_id(id_or_name)
- has_data(name)
Return True if the Group contains a Dataset object with the given name.
- Parameters
name – name of Dataset
- Returns
True if Dataset exists in Group, False if it does not exist,
or exists and is not a Dataset
- open_group(name, create=False)
Returns a new H5Group with the given name contained in the current group. If the current group does not exist in the file, it is automatically created.
- Parameters
name – the name of the group
create – creates the child group in the file if it does not exist
- Returns
a new H5Group object
- property parent
- set_attr(name, value)
- write_data(name, data, dtype=None, compression=False)
Writes the data to a Dataset contained in the group with the given name. Creates the Dataset if necessary.
- Parameters
name – name of the Dataset object
data – the data to write
dtype – optionally specify the data type, otherwise it will be
automatically determined by the data :param compression: whether to compress the data (default: False)
