The Runtime allows to enter / leave a particular purpose environment, respectively to invoke functions in a particular Purpose Environment. The current (purpose) environment does not only vary with the languages OBI (e.g. Java or C++), but also with the executed codes declared purpose type.


Operations may need to be associated with the environment(s) of a particular object. Such operations may set thread related global variables (e.g. the component- or current-context) or may acquire mutexes.



The enter / leave functionality may not be appropriate for all environments at all times. E.g. the thread affine environment does not allow to be entered, while it already has a thread associated.
