How to use a Lucene Analyzer to tokenize a String?

Question

Is there a simple way I could use any subclass of Lucene\'s Analyzer to parse/tokenize a String?

Something like:

String to_         


        

Answer 1

Based off of the answer above, this is slightly modified to work with Lucene 4.0.

public final class LuceneUtil {

  private LuceneUtil() {}

  public static List tokenizeString(Analyzer analyzer, String string) {
    List result = new ArrayList();
    try {
      TokenStream stream  = analyzer.tokenStream(null, new StringReader(string));
      stream.reset();
      while (stream.incrementToken()) {
        result.add(stream.getAttribute(CharTermAttribute.class).toString());
      }
    } catch (IOException e) {
      // not thrown b/c we're using a string reader...
      throw new RuntimeException(e);
    }
    return result;
  }

}
