Introduction to CORBA types

IDL = Interface Definition Language

ORB = Object Request Broker

Basic:

Numeric (integer, floating and fixed point, and enumerated).

Characters and strings, including wide characters.

Object references - handles to CORBA objects.

Complex:

Structures and unions, which parallel C/C++ structs and unions.

Arrays - runtime fixed-length, possibly multi-dimensional stores of multiple data

elements.

Sequences - runtime variable-length stores of multiple data elements.

"any" values store values of any data type, along with the type information

necessary to make use of that data type.

The upcoming CORBA 2.3 specification will add "object by value" capabilities,

which will allow expressing much more complex data relationships such as graphs.

Available CORBA data types:

Basic:

Numeric (integer, floating and fixed point, and enumerated).

Characters and strings, including wide characters.

Object references - handles to CORBA objects.

Complex

Structures and unions, which parallel C/C++ structs and unions.

Arrays - runtime fixed-length, possibly multi-dimensional stores of multiple data

elements. Sequences - runtime variable-length stores of multiple data elements.

"any" values store values of any data type, along with the type information

necessary to make use of that data type.

The upcoming CORBA 2.3 specification will add "object by value" capabilities,

which will allow expressing much more complex data relationships such as graphs.

Here is a sample IDL definition containing an array, a bounded sequence, and anunbounded sequence:

module ArrayModule {

struct SomeStructure {

sequence boundedChars;};

};

The arrays would be defined in Java aspublic int[] longArray;public boolean[] unboundedBools;

public char[] boundedChars;
