The 'shapefile' code in Jump is a port of the geotools code, so this should be relatively painless -- I would port the indexed shapefile reader from GT to replace the existing shapefile reader.
I you go ahead with these changes, I'd be interested in back porting this to Jump. David -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sunburned Surveyor Sent: June 6, 2007 8:07 AM To: List for discussion of JPP development and use. Subject: [JPP-Devel] A really stupid question... At some point should we rewrite the ESRI Shapefile I/O code in OpenJUMP to provide an indexed FeatureCollection by default? I'm thinking this could be used to speed up rendering of Layers, and I know it would speed up my processing of object snaps in the new CursorTool stuff. Has this already been done? If not, would there be any serious performance penalties for making this change? I'm just curious as I was looking at the Quadtree class in JTS this morning. (I'll be working with the ESRI Shapefile code from GeoTools or Deegree as part of the FeatureCache. I don't think it would be too much of a stretch to revamp the "regular" Shapefile driver in OpenJUMP while I am at it. If I do this I could make the change described above.) Thanks for the thoughts.
