== Description ==

!OrxonoxClass is the base class of all objects and interfaces in the class hierarchy. Therefore !OrxonoxClass is the direct parent of [wiki:BaseObject] and several interfaces like [wiki:Tickable] or [wiki:network/Synchronisable Synchronisable].

!OrxonoxClass itself isn't of any use for the game-logic. All functions and variables are only there to create a common base for [wiki:Identifier Identifiers] and to create the class hierarchy. Some functions are used in macros (see [wiki:CoreIncludes]).

== Inheriting from !OrxonoxClass ==

Classes inheriting from !OrxonoxClass '''must''' use '''virtual public''' derivation to avoid problems in the class-tree (diamond shape):

{{{
#!cpp
class MyInterface : virtual public OrxonoxClass
{
  ...
};

}}}

== Functions ==

 * '''Identifier''':
   * '''getIdentifier()''': Returns the [wiki:Identifier] of an object
   * '''setIdentifier('''''identifier''''')''': Sets the [wiki:Identifier] of the class (used by a macro, see [wiki:CoreIncludes]

 * '''Parents''':
   * '''getParents()''' and '''createParents()''' are functions used by macros (see [wiki:CoreIncludes]) to create the class-tree

 * '''Comparison''': see [wiki:Identifier] for more information
   * '''isA(...)'''
   * '''isExactlyA(...)'''
   * '''isChildOf(...)'''
   * '''isDirectChildOf(...)'''
   * '''isParentOf(...)'''
   * '''isDirectParentOf(...)'''

== Illustration ==

As you can see, !OrxonoxClass is on the top of the class-tree. Every other object or interface is a derivative:
