Detailed Description

Metaclass provides type inspection mechanism for Kanzi classes.

Classes deriving from Object can register information about their type, properties, methods, messages by using Metaclass and accompanying macros. Such information is used by serialization, scripting and to display friendly type information in Kanzi Studio.

Use KZ_METACLASS_BEGIN and KZ_METACLASS_END inside your class body to declare a metaclass. Serialization and functions instantiating objects use metaclass name to identify types. Use KZ_METACLASS_PROPERTY_TYPE to register a property type of your class to the metaclass. Use KZ_METACLASS_MESSAGE_TYPE to register a message type of your class to the metaclass. Use KZ_METACLASS_METHOD to register a MetaMethod of your class to the metaclass.
