Hi Steve,
Thanks for you help (just found your e-mail in list archive), your solution
works!
Below is complete working example... However, before finding your answer, I
hacked a straw-man solution, which is bad way to solve the problem:
// Hack out token - bad way!
String tmp = ts.reflectAsString(false);
String sameToken = (tmp.split(",")[0]).split("=")[1];
System.out.println("*** Same token : " + sameToken);
It is not a right way, I repeat and I give here just for fun.
---- Complete working example ----
Version matchVersion = Version.LUCENE_40; // Substitute desired Lucene
version for XY
Analyzer analyzer = new RussianAnalyzer(matchVersion); // or any other
analyzer
TokenStream ts = analyzer.tokenStream("myfield", new StringReader("some
text goes here"));
OffsetAttribute offsetAtt = ts.addAttribute(OffsetAttribute.class);
// To get token strings we need this:
CharTermAttribute termAtt = ts.addAttribute(CharTermAttribute.class);
try {
ts.reset(); // Resets this stream to the beginning. (Required)
while (ts.incrementToken()) {
// Use AttributeSource.reflectAsString(boolean)
// for token stream debugging.
System.out.println("token: " + ts.reflectAsString(true));
// Right way to get tokens
String token = termAtt.toString();
System.out.println("*** Token: " + token);
// Hack out token - bad way!
String tmp = ts.reflectAsString(false);
String sameToken = (tmp.split(",")[0]).split("=")[1];
System.out.println("*** Same token : " + sameToken);
System.out.println("token start offset: " +
offsetAtt.startOffset());
System.out.println("token end offset: " + offsetAtt.endOffset());
}
ts.end(); // Perform end-of-stream operations, e.g. set the final
offset.
} finally {
ts.close(); // Release resources associated with this stream.
analyzer.close();
}
