def xyz(self):
return 'A.xyz()', self.__class__.__name__
class B(SingleDelegated):
def foo(self):
return 'B.foo()', self.__class__.__name__
class C(MultiDelegated):
def xyz(self):
return 'C.xyz()', self.__class__.__name__
print(B(A()).foo()) # ('B.foo()', 'B')
print(B(A()).bar()) # ('A.bar()', 'A')
print(B(A()).xyz()) # ('A.xyz()', 'A')
print(C(A(), B(A())).foo()) # [('A.foo()', 'A'), ('B.foo()', 'B')]
print(C(A(), B(A())).bar()) # [('A.bar()', 'A'), ('A.bar()', 'A')]
print(C(A(), B(A())).xyz()) # ('C.xyz()', 'C')License
