Hi Michael,
Thanks for helping me but i am still unable to solved out my problem in
PolygonfeatureHelper class, I make a createPolygonFeature() which return
SimpleFeature and this method call createFeatureType()
Here is the code
public static SimpleFeature createPolyFeature(Geometry geom, String name ) {
GeometryFactory gf = new GeometryFactory();
if(geom instanceof Polygon ){
geom = new MultiPolygon(new Polygon[] {(Polygon)geom },new
GeometryFactory());
}
Object[] featureAttributes = { geom, name };
SimpleFeatureBuilder sfb = new
SimpleFeatureBuilder(createFeatureType());
sfb.add(featureAttributes);
SimpleFeature f = sfb.buildFeature(null);
return f;
}
public static SimpleFeatureType createFeatureType() {
AttributeDescriptor[] typesNew = new AttributeDescriptor[2];
AttributeTypeBuilder build = new AttributeTypeBuilder();
build.setBinding(String.class);
build.setNillable(true);
build.setLength(48);
build.defaultValue(null);
build.setName("NAME");
AttributeDescriptor descriptor = build.buildDescriptor( "NAME" );
AttributeTypeBuilder build1 = new AttributeTypeBuilder();
build1.setBinding(MultiPolygon.class);
build1.setName("the_geom");
GeometryType geometryType = build1.buildGeometryType();
GeometryDescriptor geomdescriptor = build1.buildDescriptor(
"the_geom", geometryType );
typesNew[0] = descriptor;
typesNew[1] = geomdescriptor;
SimpleFeatureTypeBuilder sf = new SimpleFeatureTypeBuilder();
sf.addAll(typesNew);
sf.setName("Poly");
SimpleFeatureType ft = sf.buildFeatureType();
return ft;
}
