Re: [udig-dev] Batchtool for generation of index files ?

Hi Stephan,

that means you can also run this from the scripting console, which
might be nice, since directly from uDig.

First you collect your shapefiles in a list and then maybe something like:

shpList.each{ file ->
    new org.geotools.data.shapefile.indexed.ShapeFileIndexer(file)
}

I never used the indexer, so the syntax might be wrong, but it should
be as simple as that.

Cheers,
Andrea
