2.2.6 Type Serialization Version 1

Type serialization version 1 is a set of extensions to the IDL/+ pickle, as specified in [C311] Part 2, IDL/NDR Pickle. Implementations of these extensions allow marshaling/unmarshaling according to the NDR transfer syntax of application-specified types by using an application-provided octet stream.

Type serialization version 1 can use either a little-endian or big-endian integer and floating-pointer byte order but MUST use the IEEE floating-point format representation and ASCII character format. See the following figure.

Figure 15: Type serialization version 1

Multiple top-level data types can be serialized into the same type serialization stream in the same way multiple parameters in a procedure are marshaling into an octet stream. A top-level data type is the data type an application provides to the implementation of these extensions to be serialized or de-serialized. A top-level data type MUST be either an NDR-constructed type or a primitive type. Each top-level data type is serialized/de-serialized as a whole, according to the rules that follow.
