                                   String[] preds)
        Description copied from interface: ChunkerContextGenerator
        Returns the contexts for chunking of the specified index.
        Specified by:
        getContext in interface ChunkerContextGenerator
        i - The index of the token in the specified toks array for which the context should be constructed.
        toks - The tokens of the sentence. The toString methods of these objects should return the token text.
        tags - The POS tags for the the specified tokens.
        preds - The previous decisions made in the taging of this sequence. Only indices less than i will be examined.
        An array of predictive contexts on which a model basis its decisions.
