Inherits From: ObjectIdentityDictionary
tf_agents.utils.object_identity.ObjectIdentityWeakKeyDictionary()
Methods
clear
clear()
D.clear() -> None. Remove all items from D.
get
get(
key, default=None
)
D.get(k[,d]) -> D[k] if k in D, else d. d defaults to None.
items
items()
D.items() -> a set-like object providing a view on D's items
keys
keys()
D.keys() -> a set-like object providing a view on D's keys
pop
pop(
key, default=__marker
)
D.pop(k[,d]) -> v, remove specified key and return the corresponding value. If key is not found, d is returned if given, otherwise KeyError is raised.
popitem
popitem()
D.popitem() -> (k, v), remove and return some (key, value) pair as a 2-tuple; but raise KeyError if D is empty.
setdefault
setdefault(
key, default=None
)
D.setdefault(k[,d]) -> D.get(k,d), also set D[k]=d if k not in D
update
update(
*args, **kwds
)
D.update([E, ]**F) -> None. Update D from mapping/iterable E and F. If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
values
values()
D.values() -> an object providing a view on D's values
__contains__

key
)
__eq__
