validSequence
public boolean validSequence(int i, TokenTag[] sequence, String[] s, String outcome)Description copied from interface:SequenceValidatorDetermines whether a particular continuation of asequenceis 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.- Specified by:
validSequencein interfaceSequenceValidator<TokenTag>- Parameters:
i- The index in theinputSequencefor which the new outcome is being proposed.sequence- The input sequence ofSequenceValidator.s- The outcomes so far in this sequence.outcome- The next proposed outcome for the outcomes sequence.- Returns:
trueif the sequence would still be valid with the new outcome,falseotherwise.
