Abstract base class for generic types.

A generic type is typically declared by inheriting from this class parameterized with one or more type variables. For example, a generic mapping type might be defined as:

class Mapping(Generic[KT, VT]):
    def __getitem__(self, key: KT) -> VT:
    # Etc.

This class can then be used as follows:

def lookup_name(mapping: Mapping[KT, VT], key: KT, default: VT) -> VT:
        return mapping[key]
    except KeyError:
        return default
property model_class: type[onegov.pas.models.Party][source]
query() Query[Party][source]
for_filter(active: bool | None = None) typing_extensions.Self[source]
