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

Bases: StoreElement[ElemMeta, None]

Persisted element that is serialized using JSON.

Methods

append_iteration_IDs	Return a copy, with additional iteration IDs.
decode	Initialise a JsonStoreElement from store element data
encode	Prepare store element 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.
