Generated decode functions are invoked through the class interface by calling the base class Decode or DecodeFrom methods. The calling sequence for this method is as follows:

   status = <object>.Decode ();

In this definition, <object> is an object of the class generated for the given production.

An OSXMLDecodeBuffer object must be passed to the <object> constructor prior to decoding. This is where the message stream containing the XML document to be decoded is specified. Several constructors are available allowing the specification of XML input from a file, memory buffer, or another stream.

The function result variable status returns the status of the decode operation. The return status will be zero if decoding is successful or a negative value if an error occurs. Return status values are documented in the C/C++ Common Functions Reference Manual and in the rtxErrCodes.h include file.
