C++Ox provides several new featues which help with the use and implementation of generic components. Although the flagship feature (concepts) was withdrawn other still remain and this presentation describes some of the new features applicable in the generic area. In particular it coverss lambda functions, the new function declaration syntax, automatically deduced types, variadic templates, and initializer lists.

Writing code applicable in more than a specific situation requires the use of some form of genericity, especially in statically typed languages. When the actual types are known only at run-time, the use of virtual functions is the way to go. However, in many situations the actually involved types are known statically and using them directly makes generic components typically both easier to use and faster. The support for static polymorphism in C++2003 is lacking some features making it often quite hard to implement generic components as well as making their use unnecessary hard. In the upcoming C++0x several of the problems are addressed. This presentation will demonstrate the use of these features as they apply both to users as well as implementers of generic components. It will only discuss features already implemented in publically available compilers (in particular in gcc), i.e. this won't be a presentation about C++ language features hopefully appearing some time in the features but it will show how the language can be used right away. Although the main focus will be core language features, the presentation will use library components new in C++Ox where applicable.
