A ridiculous class needed because UniConf::operator->() needs to return a pointer, even though that pointer is going to be dereferenced immediately anyway.
We can instantiate a temporary WvStringStar, which can then return its 'this' pointer.

WvFastString WvFastString::offset | ( | size_t | i | ) | const [inherited] |
Returns a copy of string pointed i bytes into this.
Will not make it point past the trailing null byte.

void WvFastString::do_format | ( | WvFastString & | output, |
const char * | format, | ||
const WvFastString *const * | argv | ||
) | [static, inherited] |
when this is called, we assume output.str == NULL; it will be filled.
Accept a printf-like format specifier (but more limited) and an array of WvStrings, and render them into another WvString.
For example: WvString x[] = {"foo", "blue", 1234}; WvString ret = WvString::do_format("%s%10.2s%-10s", x);
The 'ret' string will be: "foo bl1234 " Note that only 's' is supported, though integers can be rendered automatically into WvStrings. d, f, etc are not allowed!
This function is usually called from some other function which allocates the array automatically.
$ns (n > 0) is also supported for internationalization purposes. e.g. ("%$2s is arg2, and %$1s ia arg1", arg1, arg2)

WvFastString::operator const char * | ( | ) | const [inline, inherited] |
auto-convert WvString to (const char *), when needed.
Definition at line 259 of file wvstring.h.
const char* WvFastString::cstr | ( | ) | const [inline, inherited] |
return a (const char *) for this string.
The typecast operator does this automatically when needed, but sometimes (especially with varargs like in printf()) that isn't convenient enough.

WvFastString::operator QString | ( | ) | const [inherited] |
return a Qt library QString containing the contents of this string.
You need to link to libwvqt.so if you use this.

int WvFastString::num | ( | ) | const [inline, inherited] |
Return a stdc++ string with the contents of this string.
To use this, #include wvstdstring.h. used to convert WvString to int, when needed. we no longer provide a typecast, because it causes annoyance.
