[gdal-dev] Overriding IRasterIO in class derived from GDALRasterBand

Hello, Context: GDAL WKT Raster driver In my class derived from GDALRasterBand, I've overrided the methods: - IReadBlock: Fetch a block from database - IRasterIO: Should fetch several blocks, that cover an area, and add them to papoBlocks (cache). The idea is to avoid rounds in the server
