class stp.utils.typed_key_dict.TypedKey(cls: Type[ValueConcreteT])

Bases: Generic[ValueConcreteT]

A key that contains type information about the value.

__slots__ = ['concrete_cls']

value_t() → Type[ValueConcreteT]

Returns the type of the value for this key. :return: The type of the value for this key.

class stp.utils.typed_key_dict.TypedKeyDict

Bases: Generic[ValueInterfaceT], collections.abc.MutableMapping

A dictionary with type information where the key encodes information about the subclass so that the correct subclass can be retrieved without an additional instanceof check.

__setitem__(key: TypedKey[ValueConcreteT], value: ValueConcreteT) → None

__delitem__(key: TypedKey[ValueConcreteT]) → None

__len__() → int
