source: code/branches/gui/src/core/Identifier.h @ 2909

Last change on this file since 2909 was 2784, checked in by rgrieder, 16 years ago
Using std::vector instead of std::list in register/unregister Iterator/ObjectListIterator. That is approximately 6 times faster because the list has very few elements. Inlined getIdentifier() for sure by exporting the heavy part to another function. Also eliminated the need of isFirstCall() because the "static initialisation chaos" only applies to variables that cannot be evaluated at compile time.

30	@file
31	@brief Definition of the Identifier, ClassIdentifier and SubclassIdentifier classes, implementation of the ClassIdentifier and SubclassIdentifier classes.
32
33	The Identifier contains all needed informations about the class it belongs to:
34	- the name
35	- a list with all objects
36	- parents and children
37	- the factory (if available)
38	- the networkID that can be synchronised with the server
39	- all configurable variables (if available)
40
41	Every object has a pointer to the Identifier of its class. This allows the use isA(...),
42	isExactlyA(...), isChildOf(...) and isParentOf(...).
43
44	To create the class-hierarchy, the Identifier has some intern functions and variables.
45
46	Every Identifier is in fact a ClassIdentifier, but they are derived from Identifier.
47
48	SubclassIdentifier is a separated class, acting like an Identifier, but has a given class.
49	You can only assign Identifiers of exactly the given class or of a derivative to a SubclassIdentifier.
