Constructor Details

#initialize(class_mapper) ⇒ Deserializer

Pass in the class mapper instance to use when deserializing. This enables better caching behavior in the class mapper and allows one to change mappings between deserialization attempts.

Instance Method Details

#deserialize(version, source) ⇒ Object

Deserialize the source using AMF0 or AMF3. Source should either be a string or StringIO object. If you pass a StringIO object, it will have its position updated to the end of the deserialized data.

Raises:

  • (ArgumentError)

  end
end
