| EmptyTokenStream | An always exhausted token stream. | code | html |
| PatternAnalyzer | Efficient Lucene analyzer/tokenizer that preferably operates on a String rather than a java.io.Reader , that can flexibly separate text into terms via a regular expression Pattern (with behaviour identical to String#split(String) ), and that combines the functionality of org.apache.lucene.analysis.LetterTokenizer , org.apache.lucene.analysis.LowerCaseTokenizer , org.apache.lucene.analysis.WhitespaceTokenizer , org.apache.lucene.analysis.StopFilter into a single efficient multi-purpose class. | code | html |
| PatternAnalyzer.FastStringReader | A StringReader that exposes it's contained string for fast direct access. | code | html |
| PatternAnalyzer.FastStringTokenizer | Special-case class for best performance in common cases; this class is otherwise unnecessary. | code | html |
| PatternAnalyzer.PatternTokenizer | The work horse; performance isn't fantastic, but it's not nearly as bad as one might think - kudos to the Sun regex developers. | code | html |
| PrefixAndSuffixAwareTokenFilter | Links two PrefixAwareTokenFilter . | code | html |
| PrefixAwareTokenFilter | Joins two token streams and leaves the last token of the first stream available to be used when updating the token values in the second stream based on that token. | code | html |
| SingleTokenTokenStream | A TokenStream containing a single token. | code | html |
