9. IDL COMPILER

The Nokia M2M ADK includes an IDL compiler for the embedded application

development. The IDL compiler is a program that reads IDL files and produces

the necessary programming language-specific files: skeletons and stubs. These

translate message data into a form that is appropriate for cross-platform

messaging. This is described in Figure 5. The block arrows show that a client

code-calling a method on the server only sees a local method call, which is no

different from the mundane method-calls in non-distributed programming. The

ORB, together with the generated stub and skeleton code, hides the distribution

completely.
