public abstract class TranslationEngine extends java.lang.Object implements ITranslationEngine
The translation engine: two current translators are provided: Google and Microsoft, but the interface allows others. This engine is built to provide support to use multiple translators in parallel, with its own language capabilities and this engine would select the most suitable one to use.- Author:
