representing non-class members functions (C++)

[Wade Brooks]

I am using ea to trace from requirements to design and code.  We have some non-member functions (task entries and interrupt handlers) that cannot be registered with the OS with a this pointer.  I need a way to represent these in the model to show requirements allocation.  Any one have suggestions on how to handle these?

To represent non-member C++ functions in a UML model, I would use class static member functions.

You can add them directly to the related classes when it makes sense to do so or use dedicated <<Utility>> classes, e.g. to represent a set of functions defined in the local namespace of a compilation unit, for instance.
