Deprecating StopAnalyzer ENGLISH_STOP_WORDS - General replacement with an
immutable Set
---------------------------------------------------------------------------------------
Key: LUCENE-1688
URL: https://issues.apache.org/jira/browse/LUCENE-1688
Project: Lucene - Java
Issue Type: Improvement
Reporter: Simon Willnauer
Priority: Minor
Fix For: 2.9, 3.0
StopAnalyzer and StandartAnalyzer are using the static final array
ENGLISH_STOP_WORDS by default in various places. Internally this array is
converted into a mutable set which looks kind of weird to me.
I think the way to go is to deprecate all use of the static final array and
replace it with an immutable implementation of CharArraySet. Inside an analyzer
it does not make sense to have a mutable set anyway and we could prevent set
creation each time an analyzer is created. In the case of an immutable set we
won't have multithreading issues either.
in essence we get rid of a fair bit of "converting string array to set" code,
do not have a PUBLIC static reference to an array (which is mutable) and reduce
the overhead of analyzer creation.
let me know what you think and I create a patch for it.
