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.

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.
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.

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.
