As a note: As you are using Lucene 3.0 with Java 5, the casts of
addAttribute() can be removed, they were only be needed for Java 1.4
compatibility in Lucene 2.9! 3.0 uses generics, so the line in the ctor is
in Lucene 3.0:
termAtt = addAttribute(TermAttribute.class);
And it can even be shorter without the ctor at all, just use:
private final TermAttribute termAtt = addAttribute(TermAttribute.class);
(in the declaration and remove the ctor).
Happy Xmas,
Uwe
