TROXmlRpcSerializer

Overview

The TROXmlRpcSerializer class is a specialization of the TROSerializer class that provides methods for data serialization/deserialization.
This class is used inernally by the TROXmlRpcMessage class to process message data in XML-RPC format.
There is no need to use this class directly; instead, you can use the TROXmlRpcMessage class to provide support for XML-RPC messages.
