Porting Analyzer from ver 4.8.1 to ver 6.4.1

[Vincenzo D'Amore]

Hi all,

I'm porting few classes from 4.8.1 to the newer version of Lucene. I can't
understand how to convert this code, I hope you can help me:

  public  Analyzer creaAnalyzer() {
  return new Analyzer() {

  @Override
protected TokenStreamComponents createComponents(String fieldName, Reader
arg1) {
Tokenizer tokenizer = new WhitespaceTokenizer(Version.LUCENE_CURRENT, arg1);
TokenStream result = new LowerCaseFilter(Version.LUCENE_CURRENT, tokenizer);
  boolean ignorecase=true;
  result = new SynonymFilter(result, creazioneDizionario(), ignorecase);
  return new TokenStreamComponents(tokenizer,result);
  }
  };
  }

My proposal is this:

  public  Analyzer creaAnalyzer() {
  return new Analyzer() {

  @Override
+ protected TokenStreamComponents createComponents(String fieldName) {
+ Tokenizer tokenizer = new WhitespaceTokenizer();
+                               tokenizer.setReader(reader);
+  TokenStream result = new LowerCaseFilter(tokenizer);

   boolean ignorecase=true;
   result = new SynonymFilter(result, creazioneDizionario(), ignorecase);
  return new TokenStreamComponents(tokenizer,result);
  }
  };
  }

but I can't understand how to pass the "reader" to the analyzer and then to
the WhitespaceTokenizer.

Am I wrong? What do you suggest me?

Thanks in advance for your help.
Vincenzo
