  - getContext
```
String[] getContext(int idx,
                    String[] toks,
                    String[] tags,
                    String[] preds)
```
    Retrieves the contexts for chunking of the specified idx.
    
    Parameters:
    
    idx - 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 specified tokens.
    
    preds - The previous decisions made in the tagging of this sequence. Only indices less than idx will be examined.
    
    Returns:
    
    An array of predictive contexts on which a model basis its decisions.
