idmtools.assets.asset_collection module

class idmtools.assets.asset_collection.AssetCollection(assets: Union[List[TAsset], AssetCollection] = None, tags=None)

Bases: idmtools.core.interfaces.ientity.IEntity

A class that represents a collection of assets.

Parameters

assets – An optional list of assets to create the collection with.

item_type: idmtools.core.enums.ItemType = 5
assets: List[idmtools.assets.asset.Asset] = None
classmethod from_id(item_id: Union[str, uuid.UUID], platform: IPlatform = None, as_copy: bool = False, **kwargs) → AssetCollection

Loads a AssetCollection from id

Parameters

  • item_id – Asset Collection ID

  • platform – Platform Ojbect

  • as_copy – Should you load the object as a copy. When True, the contents of AC are copied, but not the id. Useful when editing ACs

  • **kwargs –

Returns

AssetCollection

classmethod from_directory(assets_directory: str, recursive: bool = True, flatten: bool = False, filters: Optional[List[Union[Callable[[TAsset], bool], Callable]]] = None, filters_mode: idmtools.core.enums.FilterMode = <FilterMode.OR: 1>, relative_path: str = None) → TAssetCollection

Fill up an AssetCollection from the specified directory. See assets_from_directory() for arguments.

Returns

A created AssetCollection object.

static assets_from_directory(assets_directory: str, recursive: bool = True, flatten: bool = False, filters: Optional[List[Union[Callable[[TAsset], bool], Callable]]] = None, filters_mode: idmtools.core.enums.FilterMode = <FilterMode.OR: 1>, forced_relative_path: str = None) → List[idmtools.assets.asset.Asset]

Create assets for files in a given directory.

Parameters

  • assets_directory – The root directory of the assets.

  • recursive – True to recursively traverse the subdirectory.

  • flatten – Put all the files in root regardless of whether they were in a subdirectory or not.

  • filters – A list of filters to apply to the assets. The filters are functions taking an Asset as argument and returning true or false. True adds the asset to the collection; False filters it out. See asset_filters().

  • filters_mode – When given multiple filters, either OR or AND the results.

  • forced_relative_path – Prefix a relative path to the path created from the root directory.

Examples

For relative_path, given the following folder structure root/a/1,txt root/b.txt and relative_path=”test”. Will return assets with relative path: test/a/1,txt and test/b.txt

Given the previous example, if flatten is also set to True, the following relative_path will be set: /1.txt and /b.txt

Returns

A list of assets.

copy() → idmtools.assets.asset_collection.AssetCollection

Copy our Asset Collection, removing ID and tags

Returns

New AssetCollection containing Assets from other AssetCollection

add_directory(assets_directory: str, recursive: bool = True, flatten: bool = False, filters: Optional[List[Union[Callable[[TAsset], bool], Callable]]] = None, filters_mode: idmtools.core.enums.FilterMode = <FilterMode.OR: 1>, relative_path: str = None)

Retrieve assets from the specified directory and add them to the collection. See assets_from_directory() for arguments.

is_editable(error=False) → bool

Checks whether Item is editable

Parameters

error – Throw error is not

Returns

True if editable, False otherwise.

add_asset(asset: Union[idmtools.assets.asset.Asset, str], fail_on_duplicate: bool = True, **kwargs)

Add an asset to the collection.

Parameters

  • asset – A string or an Asset object to add. If a string, the string will be used as the absolute_path and any kwargs will be passed to the Asset constructor

  • fail_on_duplicate – Raise a DuplicateAssetError if an asset is duplicated. If not, simply replace it.

  • **kwargs – Arguments to pass to Asset constructor when asset is a string

add_assets(assets: Union[List[TAsset], AssetCollection], fail_on_duplicate: bool = True)

Add assets to a collection

Parameters

  • assets – An list of assets as either list or a collection

  • fail_on_duplicate – Raise a DuplicateAssetError if an asset is duplicated. If not, simply replace it.

Returns:

add_or_replace_asset(asset: idmtools.assets.asset.Asset)

Add or replaces an asset in a collection

Parameters

asset – Asset to add or replace

Returns

None.

get_one(**kwargs)

Get an asset out of the collection based on the filers passed.

Examples:

>>> a = AssetCollection()
>>> a.get_one(filename="filename.txt")
Parameters

**kwargs – keyword argument representing the filters.

Returns

None or Asset if found.

delete(**kwargs) → NoReturn

Delete an asset based on keywords attributes

Parameters

**kwargs – Filter for the asset to delete.

remove(**kwargs) → NoReturn

Remove an asset from the AssetCollection based on keywords attributes

Parameters

**kwargs – Filter for the asset to remove.

pop(**kwargs) → idmtools.assets.asset.Asset

Get and delete an asset based on keywords.

Parameters

**kwargs – Filter for the asset to pop.

extend(assets: List[idmtools.assets.asset.Asset], fail_on_duplicate: bool = True) → NoReturn

Extend the collection with new assets :param assets: Which assets to add :param fail_on_duplicate: Fail if duplicated asset is included.

has_asset(absolute_path: str = None, filename: str = None) → bool

Search for asset by absolute_path or by filename

Parameters

  • filename – Destination filename

Returns

True if asset exists, False otherwise

find_index_of_asset(absolute_path: str = None, filename: str = None) → Optional[int]

Finds the index of asset by path or filename

Parameters

  • absolute_path – Path to search

  • filename – Filename to search
