public class ConcatenateGraphFilterFactory extends TokenFilterFactory
Factory forConcatenateGraphFilter
.- preserveSep:
Whether
ConcatenateGraphFilter.SEP_LABEL
should separate the input tokens in the concatenated token - preservePositionIncrements:
Whether to add an empty token for missing positions.
The effect is a consecutive
ConcatenateGraphFilter.SEP_LABEL
. When false, it's as if there were no missing positions (we pretend the surrounding tokens were adjacent). - maxGraphExpansions:
If the tokenStream graph has more than this many possible paths through, then we'll throw
TooComplexToDeterminizeException
to preserve the stability and memory of the machine.
