Subject [jira] Commented: (LUCENE-1257) Port to Java5
Date Sun, 18 Oct 2009 15:14:31 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12767072#action_12767072

Uwe Schindler commented on LUCENE-1257:
---------------------------------------

bq. More set of patches in org.apache.lucene.document

You mean not only document?

I looked through it: The o.a.l.util.cache is not ideal: The whole classes should take a <K,V>
parameter for the cache and not be fixed to <Object,Object>. This was on my list to
fix, so I would leave out the whole cache package in this patch and fix it myself.

> For my needs I've updated Lucene so that it uses Java 5 constructs. I know Java 5 migration
had been planned for 2.1 someday in the past, but don't know when it is planned now. This
patch against the trunk includes :
> - most obvious generics usage (there are tons of usages of sets, ... Those which are
commonly used have been generified)
> - PriorityQueue generification
> - replacement of indexed for loops with for each constructs
> - removal of unnececessary unboxing
> The code is to my opinion much more readable with those features (you actually *know*
what is stored in collections reading the code, without the need to lookup for field definitions
everytime) and it simplifies many algorithms.
> Note that this patch also includes an interface for the Query class. This has been done
for my company's needs for building custom Query classes which add some behaviour to the base
Lucene queries. It prevents multiple unnnecessary casts. I know this introduction is not wanted
by the team, but it really makes our developments easier to maintain. If you don't want to
use this, replace all /Queriable/ calls with standard /Query/.
