Detailed Description

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.

Member Function Documentation

void WvFastString::do_format (  WvFastString &  output, const char *  format, const WvFastString *const *  a )  [static, inherited]

when this is called, we assume output.str == NULL; it will be filled. 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.

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]

used to convert WvString to int, when needed. we no longer provide a typecast, because it causes annoyance.
