virtual RWBoolean stringToMoney(const RWCString&,
double*, RWLocale::CurrSymbol=LOCAL)
const = 0 ;
Interprets the RWCString argument as a monetary value. The currency
symbol, if any, is ignored. Negative values may be specified by the negation
symbol or by enclosing parentheses. Digit group separators are optional; if
present they are checked. Returns TRUE for a valid monetary value, FALSE for
an error. If it returns FALSE , the double* argument is untouched; otherwise it
is set to the integral number of monetary units entered (e.g. cents, in a U.S.
locale).
const RWLocale* imbue(ios& stream) const ;
Installs self in the stream argument, for later use by the operators << and >>
(e.g. in RWDate or RWTime ). The pointer may be retrieved from the stream
with the static member RWLocale::of() . In this way a locale may be passed
transparently through many levels of control to be available where needed,
without intruding elsewhere.
Static member functions static const RWLocale& of(ios&);
Returns the locale installed in the stream argument by a previous call to
RWLocale::imbue() or, if no locale was installed, the result from
RWLocale::global() .
static const RWLocale* global(const RWLocale* loc) ;
Sets the global “default” locale object to loc , returning the old object. This
object is used by RWDate and RWTime string conversion functions as a default
locale. It is set initially to refer to an instance of RWLocaleDefault .
static const RWLocale& global() ;
Returns a reference to the present global “default” locale.
