make_persistent	Save to a persistent workflow.
read_contents	Get the actual contents of the file.
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
contents	The contents of the file.
extension	The extension of the file.
path	The path to the file.

app = App(name='MatFlow', version='0.3.0a132')

property contents

The contents of the file.

property extension

The extension of the file.

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.

make_persistent(workflow, source)

Save to a persistent workflow.

Returns:

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

• contains the indices of the parameter data Zarr groups where the data is

• stored.

Parameters:

• workflow (Workflow) –

• source (Dict) –

Return type:

Tuple[str, List[int], bool]

parser

How to parse the file.

property path

The path to the file.

read_contents()

Get the actual contents of the file.

property store_contents

Whether the file’s contents are stored in the workflow’s persistent store.

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 workflow: Workflow

The owning workflow.
