Why did you choose to use a multimap for the container in the factory?

Can you store any type in the factory? That is your example shows you
storing ParentClass and the derived types plus OtherClass. Are both a
base class? Or is it two separate instances of the Factory therefore two
singleton factories available to produce objects?
