-// = DESCRIPTION
-// Code for encoding different data types
-//
-// The original code had a single static encoder function defined on
-// the CDR class that called traverse to interpret the data types.
-// This version defines a virtual method "encode" on each class and
-// avoids calling traverse.

-
-// Encode instances of arbitrary data types based only on typecode.
-// "data" points to the data type; if it's not a primitve data type,
-// the TypeCode interpreter is used to recursively encode its
-// components. "context" is the marshaling stream on which to encode
-// the data value.
