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.file.File][source]
query() Query[File][source]
for_year(year: int | None) typing_extensions.Self[source]
first_year(timezone: sedate.types.TzInfoOrName) int | None[source]
