hpcflow.sdk.persistence.base.StoreElement

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

Bases: object

Represents an element in a persistent store.

Parameters:

• id (int) – The ID of the element.

• is_pending (bool) – Whether the element has changes not yet persisted.

• index (int) – Index of the element within its parent task.

• es_idx (int) – Index of the element set containing this element.

• seq_idx (Dict[str, int]) – Value sequence index map.

• src_idx (Dict[str, int]) – Data source index map.

• task_ID (int) – ID of the task that contains this element.

• iteration_IDs (List[int]) – IDs of element-iterations that belong to this element.

• id_ (int) –

Methods

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

Attributes
