Class TranslationQueue


  • public class TranslationQueue
    extends java.lang.Object
    Translation queue object that holds the translations required from one language to another. The queue is enabled to have the same translation multiple times and only queries the translator once. Future implementations could hold a history of the most used ones, etc...
