Justin,
I have been making a lot of progress using xmlcodegen to improve
gt-xsd-gml3 GMLSchema (GEOT-2505). I modified schema.javajet so its
output avoids the 64kB method limit. I also changed the output so that
the members of GMLSchema are static, as in earlier versions.
One problem I have encountered is that the bindings for geometry
property types are now ComplexType, not AttributeType bound to JTS
Geometry. This is causing app-schema unit test failures.
The trunk version of xmlcodegen produces (even before my modifications)
a gml3 GMLSchema:
GEOMETRYPROPERTYTYPE_TYPE =
new ComplexTypeImpl(
new NameImpl("http://www.opengis.net/gml","GeometryPropertyType";),
GEOMETRYPROPERTYTYPE_TYPE_schema, false,
false,Collections.EMPTY_LIST,XSSchema.ANYTYPE_TYPE, null
);
Note that the geometry property type is now a complex type (all of which
are bound to Collection.class).
But the trunk version of gt-xsd-gml3 GMLSchema (r32244) contains:
public static final AttributeType GEOMETRYPROPERTYTYPE_TYPE = new
AttributeTypeImpl(new NameImpl(
"http://www.opengis.net/gml";, "GeometryPropertyType"), Geometry.class,
false,
false, Collections.EMPTY_LIST, XSSchema.ANYTYPE_TYPE, null);
That is, a geometry property is treated as an ordinary simple attribute
bound to a JTS Geometry, so these can be treated as atomic simple
objects and passed through the feature model. The new xmlcodegen instead
exposes the full internal complexity of geometry property types, and in
effect disables the special handling of geometry objects.
I can find no special treatment for geometries in schema.javajet (trunk
or previous versions). How is the special case for geometries applied?
How can I use the latest xmlcodegen to create an XMLSchema with geometry
property types bound to JTS geometry types? This will be necessary to
allow JTS geometry objects to be passed from data sources through the
feature model to the encoder.
Kind regards,
