Examples of joshua.decoder.ff.tm.hiero.MemoryBasedBatchGrammar

joshua.decoder.ff.tm.hiero.MemoryBasedBatchGrammar
This class implements a memory-based bilingual BatchGrammar.
The rules are stored in a trie. Each trie node has: (1) RuleBin: a list of rules matching the french sides so far (2) A HashMap of next-layer trie nodes, the next french word used as the key in HashMap @author Zhifei Li, @version $LastChangedDate: 2010-01-08 11:00:40 -0600 (Fri, 08 Jan 2010) $
