DM Smith updated LUCENE-1333:
-----------------------------
Attachment: LUCENE-1333.patch
This patch includes all the previous ones.
Note: It includes the functionality solving LUCENE-1350. If this patch is
applied before LUCENE-1350, then that issue is resolved. If it is done after
then the patch will need to be rebuilt.
I did not do the "reuse" API mentioned in LUCENE-1350.

> or to see it all at once:
> http://www.gossamer-threads.com/lists/lucene/java-dev/62851
> Issues:
> 1. JavaDoc is insufficient, leading one to read the code to figure out how to
> use the class.
> 2. Deprecations are incomplete. The constructors that take String as an
> argument and the methods that take and/or return String should *all* be
> deprecated.
> 3. The allocation policy is too aggressive. With large tokens the resulting
> buffer can be over-allocated. A less aggressive algorithm would be better. In
> the thread, the Python example is good as it is computationally simple.
> 4. The parts of the code that currently use Token's deprecated methods can be
> upgraded now rather than waiting for 3.0. As it stands, filter chains that
> alternate between char[] and String are sub-optimal. Currently, it is used in
> core by Query classes. The rest are in contrib, mostly in analyzers.
> 5. Some internal optimizations can be done with regard to char[] allocation.
> 6. TokenStream has next() and next(Token), next() should be deprecated, so
> that reuse is maximized and descendant classes should be rewritten to
> over-ride next(Token)
> 7. Tokens are often stored as a String in a Term. It would be good to add
> constructors that took a Token. This would simplify the use of the two
> together.
