Detailed Description

Defines generic classes and macros to support user data types.

DDS specifies strongly typed interfaces to read and write user data. For each data class defined by the application, there is a number of specialised classes that are required to facilitate the type-safe interaction of the application with RTI Connext.

RTI Connext provides an automatic means to generate all these type-specific classes with the rtiddsgen utility. The complete set of automatic classes created for a hypothetical user data type named Foo are shown below.

Classes auto-created for an application data type named Foo

The macros defined here declare the strongly typed APIs needed to support an arbitrary user defined data of type Foo.
