Detailed Description

This class handles decoding of individual Sentence objects (which can represent plain sentences or lattices). A single sentence can be decoded by a call to translate() and, if an InputHandler is used, many sentences can be decoded in a thread-safe manner via a single call to translateAll(), which continually queries the InputHandler for sentences until they have all been consumed and translated.

The DecoderFactory class is responsible for launching the threads.
