19 * This scanner is used to convert a string into a list of function or
20 * template arguments. Each parsed argument results in a Argument struct,
21 * that is put into an ArgumentList in declaration order.
22 * Comment blocks for arguments can also be included in the string.
23 * The argument string does not contain new-lines (except inside any
24 * comment blocks).
25 * An Argument consists of the string fields:
26 * type,name,default value, and documentation
27 * The Argument list as a whole can be pure, constant or volatile.
28 *
29 * Examples of input strings are:
30 * \verbatim
31 * "(int a,int b) const"
32 * "(const char *s="hello world",int=5) = 0"
33 * "<class T,class N>"
34 * "(char c,const char)"
35 * \endverbatim
36 *
37 * Note: It is not always possible to distinguish between the name and
38 * type of an argument. In case of doubt the name is added to the
39 * type, and the matchArgumentList in util.cpp is be used to
40 * further determine the correct separation.
