      • fromBinary

        public java.lang.Object fromBinary​(byte[] bytes,
                                           java.lang.String manifest)
        Description copied from class: SerializerWithStringManifest
        Produces an object from an array of bytes, with an optional type-hint.

        It's recommended to throw in fromBinary if the manifest is unknown. This makes it possible to introduce new message types and send them to nodes that don't know about them. This is typically needed when performing rolling upgrades, i.e. running a cluster with mixed versions for while. NotSerializableException is treated as a transient problem in the TCP based remoting layer. The problem will be logged and message is dropped. Other exceptions will tear down the TCP connection because it can be an indication of corrupt bytes from the underlying transport.
