ConcatenateGraphFilter

class ConcatenateGraphFilter(inputTokenStream: TokenStream, tokenSeparator: Char?, preservePositionIncrements: Boolean, maxGraphExpansions: Int) : TokenStream

Concatenates/Joins every incoming token with a separator into one output token for every path through the token stream (which is a graph). In simple cases this yields one token, but in the presence of any tokens with a zero positionIncrmeent (e.g. synonyms) it will be more. This filter uses the token bytes, position increment, and position length of the incoming stream. Other attributes are not used or manipulated.
