/**
* Returns a string showing the formal parameters for this method. The returned string is a comma
* separated list of parameter types, if <code>withNames</code> is true, then the returned string
* is a comma separated list of type:name.
*
* <p>Example: method is "void getX(int a, int b)", <code>withNames</code> is false, returned
* string is "int,int".
*
* <p>Example: method is "void getX(int a, int b)", <code>withNames</code> is true, returned
* string is "int a,int b".
*
* @param withNames should returned string include the formal parameter names
* @param typeAsSuffix if true and if withNames is true, name and type will be reversed, e.g.
* method is "void getX(int a, int b), returned string is "a : int, b : int"
* @param includeFinal if true, include any "final" modifier, e.g. method is "void getX(int a,
* final int b)", returned string is "int, final int", or if withNames is true, "int a, final
* int b", and if typeAsSuffix is true, "a : int, b : final int"
* @return parameters as string, see above
