hpcflow.app.Loop#

class hpcflow.app.Loop(tasks, num_iterations, name=None, non_iterable_parameters=None, termination=None)#

Bases: Loop

A loop in a workflow template.

Parameters:

tasks (list[int | WorkflowTask]) – List of task insert IDs or workflow tasks.
num_iterations (int) – Number of iterations to perform.
name (str) – Loop name.
non_iterable_parameters (list[str]) – Specify input parameters that should not iterate.
termination (v~hpcflow.app.Rule) – Stopping criterion, expressed as a rule.

Methods

`from_json_like`	Make an instance of this class from JSON (or YAML) data.
`to_dict`	Serialize this object as a dictionary.
`to_json_like`	Serialize this object as an object structure that can be trivially converted to JSON.

Attributes

`app`
`name`	The name of the loop, if one was provided.
`non_iterable_parameters`	Which parameters are not iterable.
`num_iterations`	The number of loop iterations to do.
`task_insert_IDs`	Get the list of task insert_IDs that define the extent of the loop.
`task_objects`	The tasks in the loop.
`termination`	A termination rule for the loop, if one is provided.
`workflow_template`	The workflow template that contains this loop.

classmethod from_json_like(json_like, shared_data=None)#

Make an instance of this class from JSON (or YAML) data.

Parameters:

json_like (Union[Dict, List]) – The data to deserialise.
shared_data (Optional[Dict[str, ObjectList]]) – Shared context data.

Return type:

The deserialised object.

property task_insert_IDs: Tuple[int]#: Get the list of task insert_IDs that define the extent of the loop.

property termination#: A termination rule for the loop, if one is provided.

to_json_like(dct=None, shared_data=None, exclude=None, path=None)#: Serialize this object as an object structure that can be trivially converted to JSON. Note that YAML can also be produced from the result of this method; it just requires a different final serialization step.

property workflow_template#: The workflow template that contains this loop.
