It is quite some time since I have used doxygen, but based on one of the samples here: http://en.wikipedia.org/wiki/Doxygen
You might find this Document Method snippet to be a good start point:
/**
* @param $MethodArgName$
* @return $SymbolType$
*/
Based on this sample I am assuming Doxygen works out the function make automatically, but that is just an assumption. You can easily tell Document Method to add this to the comment block.
