class hpcflow.sdk.persistence.zarr.ZarrStoreElement(id_, is_pending, index, es_idx, seq_idx, src_idx, task_ID, iteration_IDs)

Bases: StoreElement[list[Any], dict[str, list[str]]]

Represents an element in a Zarr persistent store.

Methods

append_iteration_IDs	Return a copy, with additional iteration IDs.
decode	Initialise a StoreElement from persistent element data
encode	Prepare store elements data for the persistent store.
to_dict	Prepare data for the user-facing Element object.

Attributes

id_	The ID of the element.
is_pending	Whether the element has changes not yet persisted.
index	Index of the element within its parent task.
es_idx	Index of the element set containing this element.
seq_idx	Value sequence index map.
src_idx	Data source index map.
task_ID	ID of the task that contains this element.
iteration_IDs	IDs of element-iterations that belong to this element.

Parameters:

• id_ (int) –

append_iteration_IDs(pend_IDs)

Return a copy, with additional iteration IDs.

Parameters:

pend_IDs (Iterable[int]) –

Return type:
