Description copied from interface: SequenceValidator

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.

Specified by:

validSequence in interface SequenceValidator<String>

Parameters:

i - The index in the input sequence for which the new outcome is being proposed.

sequence - The input sequence.

s - 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.
