hpcflow.app.InputValue

class hpcflow.app.InputValue(parameter, value=None, label=None, value_class_method=None, path=None, _InputValue__check_obj=True)

Bases: InputValue

An input value to a task.

Parameters:

• parameter (Parameter | SchemaInput | str) – Parameter whose value is to be specified.

• label (str) – Optional identifier to be used where the associated SchemaInput accepts multiple parameters of the specified type. This will be cast to a string.

• value (Any) – The input parameter value.

• value_class_method (How to obtain the real value.) – A class method that can be invoked with the value attribute as keyword arguments.

• path (str) – Dot-delimited path within the parameter’s nested data structure for which value should be set.

• _InputValue__check_obj (Optional[bool]) –

Methods

from_json_like	Make an instance of this class from JSON (or YAML) data.
make_persistent	Save value to a persistent workflow.
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
is_sub_value	True if the value is for a sub part of the parameter (i.e.
labelled_type	The labelled type of this input value.
normalised_inputs_path	The normalised input path without the inputs. prefix.
normalised_path	The full normalised input path.
value	The value itself.
workflow	The workflow containing this input value.
parameter	Parameter whose value is to be specified.
label	Identifier to be used where the associated SchemaInput accepts multiple parameters of the specified type.
path	Dot-delimited path within the parameter's nested data structure for which value should be set.
value_class_method	A class method that can be invoked with the value attribute as keyword arguments.

app = BaseApp(name='hpcFlow', version='0.2.0a181')

classmethod from_json_like(json_like, shared_data=None)

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

Parameters:

• json_like – The data to deserialise.

• shared_data – Shared context data.

Return type:

The deserialised object.

property is_sub_value

True if the value is for a sub part of the parameter (i.e. if path is set). Sub-values are not added to the base parameter data, but are interpreted as single-value sequences.

label

Identifier to be used where the associated SchemaInput accepts multiple parameters of the specified type.

property labelled_type

The labelled type of this input value.

make_persistent(workflow, source)

Save value to a persistent workflow.

Returns:

• String is the data path for this task input and single item integer list

• contains the index of the parameter data Zarr group where the data is

• stored.

Parameters:

• workflow (Any) –

• source (Dict) –

Return type:

Tuple[str, List[int], bool]

property normalised_inputs_path

The normalised input path without the inputs. prefix.

property normalised_path

The full normalised input path.

parameter

Parameter whose value is to be specified.

path

Dot-delimited path within the parameter’s nested data structure for which value should be set.

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.

property value

The value itself.

value_class_method

A class method that can be invoked with the value attribute as keyword arguments.

property workflow

The workflow containing this input value.
