static int | evaluatePluralExpression (const std::string &expression, ::uint64_t n) |
Utility method to evaluate a plural expression. | |
An abstract class that provides support for localized strings.
This abstract class provides the content to localized WStrings, by resolving the key to a string using the current application locale.
|
static |
Utility method to evaluate a plural expression.
This evaluates C expressions such as used by ngettext for a particular value, which can be useful to implement plural key resolution.
|
virtual |
Purges memory resources, if possible.
This is called afer event handling, and is an opportunity to conserve memory inbetween events, by freeing memory used for cached key/value bindings, if applicable.
The default implementation does nothing.
Reimplemented in Wt::WCombinedLocalizedStrings, and Wt::WMessageResourceBundle.

Resolves a key in the given locale.
This method is used by WString to obtain the UTF-8 value corresponding to a key in the given locale.
Returns a successful LocalizedString if the key could be resolved.
Implemented in Wt::WCombinedLocalizedStrings, and Wt::WMessageResourceBundle.

virtual |
Resolves the plural form of a key in the given locale.
This method is used by WString to obtain the UTF-8 value corresponding to a key in the current locale, taking into account the possibility of multiple plural forms, and chosing the right plural form based on the amount
passed.
Throws a std::logic_error if the underlying implementation does not provide support for plural internationalized strings.
Returns a successful LocalizedString if the key could be resolved.
Reimplemented in Wt::WCombinedLocalizedStrings, and Wt::WMessageResourceBundle.
