When using the Document Method refactoring on a function that has a comment in the same line, that comment is included in the $MethodQualifier$ token.
This means that int getSize() const // get the object size
{ return 3; }
gets you a $MethodQualifier$ containing "const // get the object size".
On a sidenote, the same is true if an inline comment using '/*' and '*/' is placed between the const qualifier and a ';' or '{' sign on the same line.
P.S.: the same is true if you try to document constructors with initializers on the same line, such as MyClass::MyClass(int x) : m_x(x)
