#write_object(obj, props = nil, traits = nil) ⇒ Object

Helper for writing objects inside encode_amf. If you pass in a property hash, it will use it rather than having the class mapper determine properties. You can also specify a traits hash, which can be used to reduce serialized data size or serialize things as externalizable.
