- Method Detail
  - validSequence
```
boolean validSequence(int i,
                      T[] inputSequence,
                      String[] outcomesSequence,
                      String outcome)
```
    Determines whether a particular continuation of a sequence is valid. This is used to restrict invalid sequences such as those used in start/continue tag-based chunking or could be used to implement tag dictionary restrictions.
    
    Parameters:
    
    i - The index in the inputSequence for which the new outcome is being proposed.
    
    inputSequence - The input sequence of SequenceValidator.
    
    outcomesSequence - The outcomes so far in this sequence.
    
    outcome - The next proposed outcome for the outcomes sequence.
    
    Returns:
    
    true if the sequence would still be valid with the new outcome, false otherwise.
