Caching in QueryFilter - why?

[Otis Gospodnetic <ot...@yahoo.com>]

Hi,

I'm looking at LUCENE-853, so I also looked at CachingWrapperFilter and then at QueryFilter.  I noticed QueryFilter does its own BitSet caching, and the caching part of its code is nearly identical to the code in CachingWrapperFilter.

Why is that?  Is there a good reason for that?

Thanks,
Otis

CachingWrapperFilter came along after QueryFilter.  I think I added  
CachingWrapperFilter when I realized that every Filter should have  
the capability to be cached without having to implement it.  So, the  
only reason is "legacy".  I'm perfectly fine with removing the  
caching from QueryFilter in a future major release.
