class hpcflow.app.TaskSchema(objective, actions=None, method=None, implementation=None, inputs=None, outputs=None, version=None, parameter_class_modules=None, web_doc=True, environment_presets=None, _hash_value=None)#

Bases: TaskSchema

Class to represent the inputs, outputs and implementation mechanism of a given task.

Parameters:

objective (TaskObjective | str) – This is a string representing the objective of the task schema.
actions (List[Action]) – A list of Action objects whose commands are to be executed by the task.
method (str | None) – An optional string to label the task schema by its method.
implementation (str | None) – An optional string to label the task schema by its implementation.
inputs (List[Parameter | SchemaInput] | None) – A list of SchemaInput objects that define the inputs to the task.
outputs (List[Parameter | SchemaOutput] | None) – A list of SchemaOutput objects that define the outputs of the task.
version (str | None) – The version of this task schema.
parameter_class_modules (List[str] | None) – Where to find implementations of parameter value handlers.
web_doc (bool | None) – True if this object should be included in the Sphinx documentation (normally only relevant for built-in task schemas). True by default.
environment_presets (Dict[str, Dict[str, Dict[str, Any]]] | None) – Information about default execution environments. Can be overridden in specific cases in the concrete tasks.
_hash_value (str | None) –

actions#: A list of Action objects whose commands are to be executed by the task.

app = BaseApp(name='hpcFlow', version='0.2.0a180')#

property basic_info#: Show inputs and outputs, formatted in a table.

environment_presets#: Information about default execution environments.

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.

classmethod get_by_key(key)#: Get a config-loaded task schema from a key.

get_info_html()#

Describe the task schema as an HTML document.

Return type:: str

get_key()#: Get the hashable value that represents this schema.

get_parameter_dependence(parameter)#

Find if/where a given parameter is used by the schema’s actions.

Parameters:: parameter (SchemaParameter) –

classmethod ignore_invalid_actions()#: A context manager within which invalid actions will be ignored.

implementation#: An optional string to label the task schema by its implementation.

property info#: Show inputs, outputs, and actions, formatted in a table.

property input_types#: The input types to the schema.

inputs#: A list of SchemaInput objects that define the inputs to the task.

make_persistent(workflow, source)#

Convert this task schema to persistent form within the context of the given workflow.

Parameters:

workflow (Workflow) –
source (Dict) –

Return type:

List[int]

method#: An optional string to label the task schema by its method.

property multi_input_types: List[str]#: Get a list of input types that have multiple labels.

property name#: The name of this schema.

objective#: This is a string representing the objective of the task schema.

property output_types#: The output types from the schema.

outputs#: A list of SchemaOutput objects that define the outputs of the task.

parameter_class_modules#: Where to find implementations of parameter value handlers.

property provides_parameters: Tuple[Tuple[str, str]]#: The parameters that this schema provides.

property task_template#: The template that this schema is contained in.

to_dict()#: Serialize this object as a dictionary.

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.

version#: The version of this task schema.

web_doc#: Whether this object should be included in the Sphinx documentation (normally only relevant for built-in task schemas).
