qml.data.DatasetTuple

class DatasetTuple(value=UnsetType.UNSET, info=None, *, bind=None, parent_and_key=None)

Bases: Generic[pennylane.data.base.typing_util.T], pennylane.data.base.attribute.DatasetAttribute[collections.abc.MutableMapping, tuple[pennylane.data.base.typing_util.T], tuple[pennylane.data.base.typing_util.T]]

Type for tuples.

Attributes

bind	Returns the HDF5 object that contains this attribute's data.
info	Returns the AttributeInfo for this attribute.
registry	Maps type_ids to their DatasetAttribute classes.
type_consumer_registry	Maps types to their default DatasetAttribute
type_id

bind

Returns the HDF5 object that contains this attribute’s data.

info

Returns the AttributeInfo for this attribute.

Maps type_ids to their DatasetAttribute classes.

Maps types to their default DatasetAttribute

type_id = 'tuple'

Methods

consumes_types()
copy_value()	Deserializes the mapped value from bind, and also perform a 'deep-copy' of any nested values contained in bind.
default_value()
get_value()	Deserializes the mapped value from bind.
hdf5_to_value(bind)	Parses bind into Python object.
py_type(value_type)	Determines the py_type of an attribute during value initialization, if it was not provided in the info argument.
value_to_hdf5(bind_parent, key, value)	Converts value into a HDF5 Array or Group under bind_parent[key].

classmethod consumes_types()

copy_value()

Deserializes the mapped value from bind, and also perform a ‘deep-copy’ of any nested values contained in bind.

classmethod default_value()

get_value()

Deserializes the mapped value from bind.

hdf5_to_value(bind)

Parses bind into Python object.

classmethod py_type(value_type)

Determines the py_type of an attribute during value initialization, if it was not provided in the info argument. This method returns f"{value_type.__module__}.{value_type.__name__}.

value_to_hdf5(bind_parent, key, value)

Converts value into a HDF5 Array or Group under bind_parent[key].
