Topics
	Component concept macros
	This is a list of macros for defining component in component class.
	Packaging the concepts
	To create the package you have to use set of mechanisms and macros in the separated project generating .arp file (physically it is a shared library, depending on the operating system).

Namespaces
namespace	icomp
	Package with interfaces and class used for components concept.
namespace	ipackage
	Package contains implementation for the management of ICF environment.

Classes

Detailed Description

The main use-case of this concept is to provide component-oriented software development.

This concept allows to divide application into smaller modules. At the implementation level you don't need to care about the application topology. The topology will be described separately using .acc files and can be started using runtime environment over ICF tool or compiled to C++ code using Icrc compiler. Additionally you can use component simulation to use components as "normal" classes.

Characteristics of a component

• Implements a set of interfaces.
• Can have static attributes.
• Can access other components via their interfaces.
• Can create other components dynamically.
• Can have sub-elements that also implement a set of interfaces.

Creation of components

• Components can be programmed in C++ as a class derived from icomp::CComponentBase and has the macro I_BEGIN_COMPONENT in it.
• With topology description you can build a component from several components - such a component has all the characteristics of a component.

Tools used in this context

• There is a tool for graphical definition of the component topology: Compositor.exe.
• The Icf.exe tool is available to test a prototype topology.
• The translation tool Icrc.exe generates C++ code for direct use of the topology file.
