Serializer discards a class name in TypedHash

[Teshootub7]

Hi,

When I deserialize AMF3 data, modify it, and then serialize it, I noticed class names in AMF3 Objects is discarded.
For example:

require 'rocketamf'⏎
amf3_object_with_classname = "\x0a\x0b\x13ClassName\x01\x01"⏎
data = RocketAMF.deserialize( amf3_object_with_classname, 3 )⏎
p data.type # => "ClassName"⏎
data = RocketAMF.deserialize( RocketAMF.serialize( data, 3 ), 3 )⏎
p data.type # => ""⏎

I expect the class name "ClassName" is kept on serialization, but RocketAMF.serialize discards the class name and it will be an empty string instead. I know it can be avoided by mapping the class names, but it would be very convenient if class names in AMF3 Object is kept out-of-the-box. Especially, a class name stored in TypedHash should be kept because TypedHash is used to store the AMF3 Object and its class name.

I hope the following spec to be passed.

diff --git a/spec/class_mapping_spec.rb b/spec/class_mapping_spec.rb
index 16ff524..1a674b7 100644

+    it "should return the same AS class as of TypedHash" do
+      @mapper.get_as_class_name(RocketAMF::Values::TypedHash.new("UnmappedClass")).should == 'UnmappedClass'
+    end

Could you explain how mapping the class names? I have array expect object :(
