Package pyamf :: Module amf3

Module amf3

AMF3 implementation.

AMF3 is the default serialization for ActionScript 3.0 and provides various advantages over AMF0, which is used for ActionScript 1.0 and 2.0. It adds support for sending int and uint objects as integers and supports data types that are available only in ActionScript 3.0, such as ByteArray and ArrayCollection.
