idmtools.assets.asset module#

idmtools asset class definition.

class idmtools.assets.asset.Asset(absolute_path: str | None = None, relative_path: str | None = <property object>, filename: str | None = <property object>, content: dataclasses.InitVar[typing.Any] = <property object>, persisted: bool = False, handler: ~typing.Callable = <class 'str'>, download_generator_hook: ~typing.Callable | None = None, checksum: dataclasses.InitVar[typing.Any] = <property object>)[source]#

Bases: object

A class representing an asset. An asset can either be related to a physical asset present on the computer or directly specified by a filename and content.

absolute_path: str | None = None#: The absolute path of the asset. Optional if filename and content are given.

persisted: bool = False#: Persisted tracks if item has been saved

handler#

Handler to api

alias of str

download_generator_hook: Callable = None#: Hook to allow downloading from platform

property checksum#: Checksum of asset. Only required for existing assets

property extension: str#

Returns extension of asset.

Returns:: Extension

Notes

This does not preserve the case of the extension in the filename. Extensions will always be returned in lowercase.

property filename#: Name of the file. Optional if absolute_path is given.

property relative_path#: The relative path (compared to the simulation root folder).

property bytes#

Bytes is the content as bytes.

Returns:: None

property length#

Get length of item.

Returns:: Length of the content

property content#: The content of the file. Optional if absolute_path is given.

deep_equals(other: Asset) → bool[source]#

Performs a deep comparison of assets, including contents.

Parameters:: other – Other asset to compare
Returns:: True if filename, relative path, and contents are equal, otherwise false

download_generator() → Generator[bytearray, None, None][source]#

A Download Generator that returns chunks of bytes from the file.

Returns:: Generator of bytearray
Raises:: ValueError - When there is not a download generator hook defined –

Notes

TODO - Add a custom error with doclink.

download_stream() → BytesIO[source]#

Get a bytes IO stream of the asset.

Returns:: BytesIO of the Asset

__init__(absolute_path: str | None = None, relative_path: str | None = <property object>, filename: str | None = <property object>, content: dataclasses.InitVar[typing.Any] = <property object>, persisted: bool = False, handler: ~typing.Callable = <class 'str'>, download_generator_hook: ~typing.Callable | None = None, checksum: dataclasses.InitVar[typing.Any] = <property object>) → None#

download_to_path(dest: str, force: bool = False)[source]#

Download an asset to path. This requires loadings the object through the platform.

Parameters:

dest – Path to write to. If it is a directory, the asset filename will be added to it
force – Force download even if file exists

Returns:

None

calculate_checksum() → str[source]#

Calculate checksum on asset. If previous checksum was calculated, that value will be returned.

Returns:: Checksum string

short_remote_path() → str[source]#

Returns the short remote path. This is the join of the relative path and filename.

Returns:: Remote Path + Filename

save_as(dest: str, force: bool = False)[source]#

Download asset object to destination file. :param dest: the file path :param force: force download

Returns:: None

save_md5_checksum()[source]#: Save the md5 checksum of the asset to a file in the same directory as the asset. :returns: None
