Uwe Schindler updated LUCENE-1796:
----------------------------------
Attachment: LUCENE-1796.patch
New patch that optimizes the iteration over the AttributeImpls using the
computed State linked list. This also adds the default buffer size to
KeywordTokenizer, that got lost during the move to the new API.
To test performance, I reactivated the clearAttributes() call in CharTokenizer.
If this is now all ok, I would like to fix this issue as soon as possible to be
able to do more perf testing with the optimized impls. The big hammer of
isMethodOverridden is now removed and speed came back to the original one (with
some small slowdown caused by mixing old and new TokenFilters together).
