Method Summary

Modifier and Type	Method and Description
boolean	validSequence(int i, T[] inputSequence, java.lang.String[] outcomesSequence, java.lang.String outcome) Determines whether a particular continuation of a sequence is valid.

Method Detail

validSequence

boolean validSequence(int i,
                      T[] inputSequence,
                      java.lang.String[] outcomesSequence,
                      java.lang.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 input sequence for which the new outcome is being proposed.

inputSequence - The input sequence.

outcomesSequence - The outcomes so far in this sequence.

outcome - The next proposed outcome for the outcomes sequence.

Returns:

true is the sequence would still be valid with the new outcome, false otherwise.
