PostgisDatastore createSchema creates table with wrong geometrytype
-------------------------------------------------------------------
Key: GEOT-3218
URL: http://jira.codehaus.org/browse/GEOT-3218
Project: GeoTools
Issue Type: Bug
Components: data postgis
Affects Versions: 2.6.4
Reporter: Roy Braam
Assignee: Justin Deoliveira
The PostgisDataStore.createSchema(SimpleFeatureType) is creating the wrong
insert script for the geometry table.
The cause is the function:
{noformat}
private String getGeometrySQLTypeName(Class type) {
String res = (String) GEOM_CLASS_MAPPINGS.get(type);
if (res == null) {
throw new RuntimeException("Unknown type name for class " + type
+ " please update GEOMETRY_MAPPINGS");
}
return res;
}
{noformat}
That uses the static GEOM_CLASS_MAPPINGS:
But that one is created with the GEOM_TYPE_MAP like:
{noformat} static {
// init the inverse map
Set keys = GEOM_TYPE_MAP.keySet();
for (Iterator it = keys.iterator(); it.hasNext();) {
String name = (String) it.next();
Class geomClass = (Class) GEOM_TYPE_MAP.get(name);
GEOM_CLASS_MAPPINGS.put(geomClass, name);
}
}
{noformat}
The GEOM_CLASS_MAPPINGS looks like this:
{noformat}
static {
GEOM_TYPE_MAP.put("GEOMETRY", Geometry.class);
GEOM_TYPE_MAP.put("POINT", Point.class);
GEOM_TYPE_MAP.put("POINTM", Point.class);
GEOM_TYPE_MAP.put("LINESTRING", LineString.class);
GEOM_TYPE_MAP.put("LINESTRINGM", LineString.class);
GEOM_TYPE_MAP.put("POLYGON", Polygon.class);
GEOM_TYPE_MAP.put("POLYGONM", Polygon.class);
GEOM_TYPE_MAP.put("MULTIPOINT", MultiPoint.class);
GEOM_TYPE_MAP.put("MULTIPOINTM", MultiPoint.class);
GEOM_TYPE_MAP.put("MULTILINESTRING", MultiLineString.class);
GEOM_TYPE_MAP.put("MULTILINESTRINGM", MultiLineString.class);
GEOM_TYPE_MAP.put("MULTIPOLYGON", MultiPolygon.class);
GEOM_TYPE_MAP.put("MULTIPOLYGONM", MultiPolygon.class);
GEOM_TYPE_MAP.put("GEOMETRYCOLLECTION", GeometryCollection.class);
GEOM_TYPE_MAP.put("GEOMETRYCOLLECTIONM", GeometryCollection.class);
// SQL MM "Curve" extensions
GEOM_TYPE_MAP.put("CIRCULARSTRING", LineString.class);
GEOM_TYPE_MAP.put("COMPOUNDCURVE", LineString.class);
GEOM_TYPE_MAP.put("CURVEPOLYGON", Polygon.class);
}
{noformat}
The result is something like this:
{noformat}
GEOM_CLASS_MAPPINGS=
{
Polygon.class:"CURVEPOLYGON",
LineString.class:"COMPOUNDCURVE",
GeometryCollection.class:"GEOMETRYCOLLECTIONM",
MultiPolygon.class:"MULTIPOLYGONM",
MultiLineString.class:"MULTILINESTRINGM",
Point.class:"POINTM",
Geometry.class:"GEOMETRY"
}
{noformat}
So the command
{noformat}
GEOM_CLASS_MAPPINGS.get(LineString.class);
{noformat}
results in a "COMPOUNDCURVE".
