gemd.entity.base_entity module

Base class for all entities.

class gemd.entity.base_entity.BaseEntity(uids: MutableMapping[str, str], tags: Iterable[str])

Bases: DictSerializable

Base class for any entity, which includes objects and templates.

typ

alias of NotImplementedError

add_uid(scope: str, uid: str)

Add a uid.

Parameters
  • scope (str) – scope of the uid

  • uid (str) – Unique identifier

all_dependencies() Set[Union[BaseEntityType, LinkByUIDType]]

Return a set of all immediate dependencies (no recursion).

as_dict() Dict[str, Any]

Convert the object to a dictionary.

Returns

A dictionary representation of the object, where the keys are its fields.

Return type

dict

static build(d: Mapping[str, Any]) DictSerializableType

Build an object from a JSON dictionary.

This differs from from_dict in that the values themselves may also be dictionaries corresponding to serialized DictSerializable objects.

Parameters

d (dict) – The object as a serialized dictionary.

Returns

The deserialized object.

Return type

DictSerializable

dump() Dict[str, Any]

Convert the object to a JSON dictionary, so that every entry is serialized.

Uses the json encoder client, so objects with uids are converted to LinkByUID dictionaries.

Returns

A string representation of the object as a dictionary.

Return type

str

classmethod from_dict(d: Mapping[str, Any]) DictSerializableType

Reconstitute the object from a dictionary.

Parameters

d (dict) – The object as a dictionary of key-value pairs that correspond to the object’s fields.

Returns

The deserialized object.

Return type

DictSerializable

Generate a ~gemd.entity.link_by_uid.LinkByUID for this object.

Parameters
  • scope (str, optional) – scope of the uid to get

  • allow_fallback (bool) – whether to grab another scope/id if chosen scope is missing (Default: False).

Return type

LinkByUID

skip = {}
property tags: List[str]

A collection of structured labels.

Tags are hierarchical strings that store information about an entity. They can be used for filtering and discoverability.

property uids: Dict[str, str]

A collection of unique IDs.

Requirements for and the value of unique IDs are discussed here.
