Hi,
I have found answer, and I would like to share with you
It is only need to override getFeatureReader( String typeName, Query
query) from AbstractDataStore (you may do it in gt-property GeoTools
project in PropertyDataStore class)
and just add:
Filter filter = query.getFilter();
if (filter instanceof org.geotools.renderer.lite.FastBBOX) {
FastBBOX filterBBox = (FastBBOX)filter;
...
}
of course it is need to change FastBBOX visibility to public
and after this you can:
filterBBox.getMinX();
filterBBox.getMaxX();
filterBBox.getMinY();
filterBBox.getMaxY();
Is there a way to do this without changing FastBBOX class?
Regards,
Rafal O.
