TROPostMessageSerializer

Overview

The TROPostMessageSerializer class implements a serializer that encodes and decodes data in the format suitable to be transferred using the HTTP POST command. It introduces no new visible members compared to its superclass. Please refer to the TROSerializer documentation for a detailed description of the class memebers.
