Subject Re: AMF3 Serialization Benchmark (GraniteDS 3.1.0.M1 vs. BlazeDS 4.0.0)
Date Tue, 03 Jun 2014 10:52:56 GMT
See https://github.com/fwolff/flex-vectors-example and especially
https://github.com/fwolff/flex-vectors-example/blob/master/java/org/granite/example/vectors/java/VectorService.java,
which shows how to serialize java arrays / collections as AMF vectors
(sorry this feature isn't well documented yet).

Franck.
