id (int) – The ID of this element.
is_pending (bool) – Whether this element is pending execution.
task (WorkflowTask) – The task this is part of the enactment of.
index (int) – The index of this element.
es_idx (int) – The index within the task of the element set containing this element.
iterations (list[dict]) – Data for creating iteration objects.
id_ (int) –

- property action_runs: List[ElementActionRun]#
A list of element action runs from the latest iteration, where only the final run is taken for each element action.
- property actions: Dict[app.ElementAction]#
The actions of this element (or its most recent iteration).
- property dir_name#
The name of the directory for containing temporary files for this element.
- property element_set#
The element set containing this element.
- property element_set_idx: int#
The index within the task of the element set containing this element.
- get(path=None, action_idx=None, run_idx=-1, default=None, raise_on_missing=False, raise_on_unset=False)#
Get element data of the most recent iteration from the persistent store.
- get_EAR_dependencies(as_objects=False)#
Get EARs that the most recent iteration of this element depends on.
- Parameters:
as_objects (bool) –
- Return type:
- get_data_idx(path=None, action_idx=None, run_idx=-1)#
Get the data index of the most recent element iteration.
- get_dependent_EARs(as_objects=False)#
Get EARs that depend on the most recent iteration of this element.
- Parameters:
as_objects (bool) –
- Return type:
- get_dependent_element_iterations(as_objects=False)#
Get element iterations that depend on the most recent iteration of this element.
- Parameters:
as_objects (bool) –
- Return type:
- get_dependent_elements(as_objects=False)#
Get elements that depend on the most recent iteration of this element.
- get_dependent_elements_recursively(task_insert_ID=None)#
Get downstream elements that depend on this element, including recursive dependencies.
Dependencies are resolved using the initial iteration only. This method is used to identify from which element in the previous iteration a new iteration should be parametrised.
- Parameters:
task_insert_ID – If specified, only return elements from this task.
- get_dependent_tasks(as_objects=False)#
Get tasks that depend on the most recent iteration of this element.
- Parameters:
as_objects (bool) –
- Return type:
List[int | WorkflowTask]
- get_element_dependencies(as_objects=False)#
Get elements that the most recent iteration of this element depends on.
- get_element_iteration_dependencies(as_objects=False)#
Get element iterations that the most recent iteration of this element depends on.
- Parameters:
as_objects (bool) –
- Return type:
- get_input_dependencies()#
Get locally defined inputs/sequences/defaults from other tasks that this the most recent iteration of this element depends on.
- get_parameter_sources(path=None, action_idx=None, run_idx=-1, typ=None, as_strings=False, use_task_index=False)#
“Get the parameter sources of the most recent element iteration.
- get_sequence_value(sequence_path)#
Get the value of a sequence that applies.
- get_task_dependencies(as_objects=False)#
Get tasks (insert ID or WorkflowTask objects) that the most recent iteration of this element depends on.
Dependencies may come from either elements from upstream tasks, or from locally defined inputs/sequences/defaults from upstream tasks.
- Parameters:
as_objects (bool) –
- Return type:
