Great idea! I have implemented it partically, just fetching some fields we needed, and resuing feature object, directly reading geometry(WKB foramt) object from shapefile file, and resuing geometry object.
maybe, we can read a block from shapefile one time, and parse it to some geoemtry objects, and this memory block should be resuing. these method will speed up reading geometry objects and attribute from DBF and shapefile. --- 10年7月24日，周六, [email protected] <[email protected]> 写道： 发件人: [email protected] <[email protected]> 主题: gdal-dev Digest, Vol 74, Issue 64 收件人: [email protected] 日期: 2010年7月24日,周六,上午12:00 Send gdal-dev mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit http://lists.osgeo.org/mailman/listinfo/gdal-dev or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of gdal-dev digest..."
