- property EAR_IDs_flat#
The EAR IDs.
- property EARs_initialised#
Whether or not the EARs have been initialised.
- property action_runs: List[ElementActionRun]#
A list of element action runs, where only the final run is taken for each element action.
- property actions: Dict[app.ElementAction]#
The actions of this iteration.
- app = App(name='MatFlow', version='0.3.0a132')#
- property data_idx#
The overall element iteration data index, before resolution of EARs.
- property element#
The element this is an iteration of.
- get(path=None, action_idx=None, run_idx=-1, default=None, raise_on_missing=False, raise_on_unset=False)#
Get element data from the persistent store.
- get_EAR_dependencies(as_objects=False)#
Get EARs that this element iteration depends on (excluding EARs of this element iteration).
- Parameters:
as_objects (bool | None) –
- Return type:
- get_data_idx(path=None, action_idx=None, run_idx=-1)#
Get the data index.
- get_dependent_EARs(as_objects=False)#
Get EARs of downstream iterations and tasks that depend on this element iteration.
- Parameters:
as_objects (bool) –
- Return type:
- get_dependent_element_iterations(as_objects=False)#
Get elements iterations of downstream iterations and tasks that depend on this element iteration.
- Parameters:
as_objects (bool) –
- Return type:
- get_dependent_elements(as_objects=False)#
Get elements of downstream tasks that depend on this element iteration.
- get_dependent_tasks(as_objects=False)#
Get downstream tasks that depend on this element iteration.
- Parameters:
as_objects (bool) –
- Return type:
List[int | WorkflowTask]
- get_element_dependencies(as_objects=False)#
Get elements that this element iteration depends on.
- get_element_iteration_dependencies(as_objects=False)#
Get element iterations that this element iteration depends on.
- Parameters:
as_objects (bool) –
- Return type:
- get_input_dependencies()#
Get locally defined inputs/sequences/defaults from other tasks that this element iteration depends on.
- get_parameter_names(prefix)#
Get parameter types associated with a given prefix.
For example, with the prefix “inputs”, this would return [‘p1’, ‘p2’] for a task schema that has input types p1 and p2. For inputs, labels are ignored. For example, for a task schema that accepts two inputs of the same type p1, with labels one and two, this method would return (for the “inputs” prefix): [‘p1[one]’, ‘p1[two]’].
This method is distinct from Action.get_parameter_names in that it returns schema-level inputs/outputs, whereas Action.get_parameter_names returns action-level input/output/file types/labels.
- get_parameter_sources(path=None, action_idx=None, run_idx=-1, typ=None, as_strings=False, use_task_index=False)#
Get the origin of parameters.
- get_resources(action, set_defaults=False)#
Resolve specific resources for the specified action of this iteration, considering all applicable scopes.
- get_resources_obj(action, set_defaults=False)#
Get the resources for an action (see
get_resources()
) as a searchable model.- Parameters:
- Return type:
- get_task_dependencies(as_objects=False)#
Get tasks (insert ID or WorkflowTask objects) that this element iteration depends on.
Dependencies may come from either elements from upstream tasks, or from locally defined inputs/sequences/defaults from upstream tasks.
