Determines whether the string on the left side of the operator is less than the string on the right side.
friend bool operator<(
const CStringT& str1,
const CStringT& str2
) throw();
friend bool operator<(
const CStringT& str1
PCXSTR psz2
) throw();
friend bool operator<(
PCXSTR psz1
const CStringT& str2
) throw();
Parameters
str1
A CStringT for comparison.str2
A CStringT for comparison.psz1
A pointer to a null-terminated string for comparison.psz2
A pointer to a null-terminated string for comparison.
Remarks
A lexicographical comparison between strings, character by character until:
It finds two corresponding characters unequal, and the result of their comparison is taken as the result of the comparison between the strings.
It finds no inequalities, but one string has more characters than the other, and the shorter string is considered less than the longer string.
It finds no inequalities and finds that the strings have the same number of characters, and so the strings are equal.
Example
// typedef CStringT<TCHAR, StrTraitATL<TCHAR, ChTraitsCRT<TCHAR>>> CAtlString;
CAtlString s1(_T("cat")), s2(_T("cats")), s3(_T("dogs"));
ASSERT(s1 < _T("dog"));
ASSERT(s1 < _T("cats"));
ASSERT(s2 < _T("cats and dogs"));
ASSERT(s2 < s3);
