Examples of org.apache.lucene.analysis.CachingTokenFilter.reset()

org.apache.lucene.analysis.CachingTokenFilter.reset()
Rewinds the iterator to the beginning of the cached list.
Note that this does not call reset() on the wrapped tokenstream ever, even the first time. You should reset() the inner tokenstream before wrapping it with CachingTokenFilter.

    TokenStream source = null;
    try {
      source = analyzer.tokenStream(field, queryText);
      source.reset();
      buffer = new CachingTokenFilter(source);
      buffer.reset();


      if (buffer.hasAttribute(TermToBytesRefAttribute.class)) {
        termAtt = buffer.getAttribute(TermToBytesRefAttribute.class);
      }
      if (buffer.hasAttribute(PositionIncrementAttribute.class)) {

    buffer.reset();


    BytesRef bytes = termAtt == null ? null : termAtt.getBytesRef();
