Implementation Overview

This chapter gives you an overview of how MICO implements the CORBA 2 specification, the implementation components it consists of and how those components are being used.

A CORBA 2 implementation consists of the following logical components:

• the Object Request Broker (ORB) provides for object location and method invocation.
• the interface repository stores runtime type information.
• one or more object adapters which form the interface between object implementations and the ORB; at least the Basic Object Adapter (BOA) has to be provided, part of which is the implementation repository that stores information about how to activate object implementations.
• the IDL compiler generates client stubs, server skeletons and marshalling code from a CORBA IDL according to the supported language mappings.

Each of these logical components has to be mapped to one or more implementation components, which are described in the next sections.
