Class DeferredTranslatorFactory

  • All Implemented Interfaces:
    TranslatorFactory
    public class DeferredTranslatorFactory
extends java.lang.Object
implements TranslatorFactory
    A TranslatorFactory that creates the Translator based on serving.properties file.

    The Criteria API cannot access serving.properties files before it's downloaded. A DeferredTranslatorFactory assumes serving.properties will provide proper Translator. If no translatorFactory is provided in serving.properties, a TranslateException will be thrown.
