Detailed Description

Class providing information on plural forms.

Languages known to this class are identified by a languageId string which is "default" for the default translation, otherwise the value of /sim/intl/locale[n]/language-id for the selected locale.

Plural forms are identified by an index that starts from 0. Whenever possible, we use the same order as Qt Linguist for plural forms in a given language.

When retrieving a translation that has plural form, one obtains the index of the plural form to use by providing a “cardinal number” (a number of “items” of any kind, which could be concrete objects or abstract things) to a language-dependent function. This class contains a map from languageId strings to such functions, which is used by getPluralFormIndex().
