IDL 4.2 · §7.4.13.4.1

Struct

A struct is an ordered aggregate of named members of arbitrary type — the workhorse of DDS topic types. Extensibility (@final / @appendable / @mutable) controls how readers and writers with differing definitions interoperate.

Example

@appendable
struct Point {
  @key long id;
  double     x;
  double     y;
};
