  • 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.
  • Property svn:eol-style set to native

[2171]30    @file
[790]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
[1024]36     - parents and children
[790]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(...),
[871]42    isExactlyA(...), isChildOf(...) and isParentOf(...).
[790]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.
