Class SDLDataStore

java.lang.Object

nl.b3p.geotools.data.sdl.SDLDataStore

All Implemented Interfaces:

org.geotools.data.DataAccess<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>, org.geotools.data.DataStore, org.geotools.data.FileDataStore

public class SDLDataStore
extends Object
implements org.geotools.data.FileDataStore

DataStore for reading a SDL file produced by Autodesk SDF Loader which supports the legacy SDF format (which FDO/MapGuide Open Source can't read). The SDF component toolkit can read those but COM objects are perhaps a lesser evil than Runtime.exec()'ing the SDF Loader. Note that a single SDL file can contain point, line and polygon SimpleFeatures. Although many files will only contain a single type, the parser can only determine this by looking through the entire file - which is not advisable in a streaming API. The same is true for a file containing only polygons or also multipolygons etc. Therefore always the same SimpleFeature schema is used: the_geom_point: Point (SDL does not contains MultiPoints) the_geom_line: MultiLineString (getNumGeometries() can be 1) the_geom_polygon: MultiPolygons (getNumGeometries() can be 1, can contain holes) Where only one of three is not null. The attributes are always the same: key: String name: String urlLink: String entryLineNumber: Integer parseError: Boolean error: String Note that especially polygons can contain parse errors due to randomly duplicated coordinates. Not much that can be done about that, because sometimes it is not possible to determine if the coordinate is duplicated or a closing coordinate of a subgeometry. See the SDF Loader Help for the description of the SDL file format.
