Complex Data Types

This next example won't do much as a practical application. However, it illustrates how to use some of the complex data types that are available in CORBA IDL. Listing 19.8 shows the IDL for the Advanced Data Types (ADTs).

Listing 19.8. ADT.idl
// ADT IDL file

typedef string Identifier;

enum EnumType
{
  first,
  second,
  third
};

struct StructType
{
  short s;
  long l;
  Identifier i; }; const unsigned long ArraySize = 3; typedef StructType StructArray[ArraySize]; typedef sequence<StructType> StructSequence; interface ADT { void Test1(in Identifier st, in EnumType myEnum, inout StructType myStruct); void Test2(out StructType myStruct, in StructArray ...
