[Biojava-dev] FeatureFilter.OverlapsExtent

[Thomas Down]

Hi,

I've been trying to tidy up javadoc and stuff in the various 
FeatureFilter-related classes and spotted a new filter implementation 
called FeatureFilter.OverlapsExtent.  This seems to be redundant with 
the existing FeatureFilter.ShadowOverlapsLocation (which was in biojava 
1.3) but has a couple of problems:

    - There's no corresponding ContainsExtent
    - It's missing all the hooks which make FeatureFilter query 
optimization work.

Right now, there only seems to be one use of this filter, in 
FeatureBlockSequenceRenderer.  Does anyone object if I kill it off and 
switch FeatureBlockSequenceRenderer over to ShadowOverlapsLocation?

       Thomas.
