class hpcflow.sdk.persistence.zarr.ZarrStoreElementIter(id_, is_pending, element_ID, EARs_initialised, EAR_IDs, data_idx, schema_parameters, loop_idx=<factory>)#

Bases: StoreElementIter

Represents an element iteration in a Zarr persistent store.

Methods

`append_EAR_IDs`	Return a copy, with additional EAR IDs.
`decode`	Initialise a StoreElementIter from persistent element iteration data
`encode`	Prepare store element iteration data for the persistent store.
`set_EARs_initialised`	Return a copy with EARs_initialised set to True.
`to_dict`	Prepare data for the user-facing ElementIteration object.
`update_loop_idx`	Return a copy, with the loop index updated.

Attributes

`id_`	The ID of this element iteration.
`is_pending`	Whether the element iteration has changes not yet persisted.
`element_ID`	Which element is an iteration for.
`EARs_initialised`	Whether EARs have been initialised for this element iteration.
`EAR_IDs`	Maps task schema action indices to EARs by ID.
`data_idx`	Overall data index for the element-iteration, which maps parameter names to parameter data indices.
`schema_parameters`	List of parameters defined by the associated task schema.
`loop_idx`	What loops are being handled here and where they're up to.

Parameters:

id_ (int) –
is_pending (bool) –
element_ID (int) –

EAR_IDs: Dict[int, List[int]]#: Maps task schema action indices to EARs by ID.

EARs_initialised: bool#: Whether EARs have been initialised for this element iteration.

append_EAR_IDs(pend_IDs)#

Return a copy, with additional EAR IDs.

Parameters:

self (AnySElementIter) –
pend_IDs (Dict[int, List[int]]) –

Return type:

AnySElementIter

data_idx: Dict[str, int]#: Overall data index for the element-iteration, which maps parameter names to parameter data indices.

set_EARs_initialised()#

Return a copy with EARs_initialised set to True.

Parameters:: self (AnySElementIter) –
Return type:: AnySElementIter

to_dict(EARs)#: Prepare data for the user-facing ElementIteration object.

update_loop_idx(loop_idx)#

Return a copy, with the loop index updated.

Parameters:

self (AnySElementIter) –
loop_idx (Dict[str, int]) –

Return type:

AnySElementIter
