Vladislav Glinskiy resolved OLINGO-1392.
----------------------------------------
Resolution: Not A Problem
> Olingo V4 client reports invalid value type for `Edm.GeometryCollection` and
> `Edm.GeographyCollection` JSON values
> ------------------------------------------------------------------------------------------------------------------
>
> Key: OLINGO-1392
> URL: https://issues.apache.org/jira/browse/OLINGO-1392
> Project: Olingo
> Issue Type: Bug
> Components: odata4-client
> Reporter: Vladislav Glinskiy
> Priority: Major
> Fix For: (Java) V4 4.7.0
>
>
> Olingo V4 client reports value type for `Edm.GeometryCollection` and
> `Edm.GeographyCollection` OData types as `ValueType.COMPLEX` instead of
> expected `ValueType.GEOSPATIAL`.
> Debugging shows that the client uses
> [JsonDeserializer|https://github.com/apache/olingo-odata4/blob/master/lib/client-core/src/main/java/org/apache/olingo/client/core/serialization/JsonDeserializer.java#L64]
> which does not work correctly with values of `Edm.GeometryCollection` and
> `Edm.GeographyCollection` OData types, such as:
> {code:java}
> {
> "GeometryCollectionField":{
> "type":"GeometryCollection",
> "geometries":[
> {
> "type":"Point",
> "coordinates":[
> 1.0,
> 1.0
> ],
> "crs":{
> "type":"name",
> "properties":{
> "name":"EPSG:4326"
> }
> }
> }
> ],
> "crs":{
> "type":"name",
> "properties":{
> "name":"EPSG:4326"
> }
> }
> }
> }
> {code}
> [I created a unit test to reproduce the
> issue|https://github.com/vladglinskiy/olingo-odata4/commit/4613e2a4f266bf99f56dd4cac2d58df0c03efa1d#diff-c2bf3c9859b1f7113d0296bc1b6dcb5dR58]:
> {code:java}
> @Test
> public void toEntityWithGeometryCollectionField() throws Exception {
> GeospatialCollection collection = new
> GeospatialCollection(Geospatial.Dimension.GEOMETRY, SRID.valueOf("4326"),
>
> Collections.<Geospatial>singletonList(POINT));
> ByteArrayOutputStream output = new ByteArrayOutputStream();
> OutputStreamWriter writer = new OutputStreamWriter(output,
> Constants.UTF8);
> Entity entity = new Entity();
> final Property propertyResource = new Property();
> propertyResource.setName("GeometryCollectionField");
> propertyResource.setValue(ValueType.GEOSPATIAL, collection);
> entity.getProperties().add(propertyResource);
> SERIALIZER.write(writer, new ResWrap(null, null, entity));
> System.out.println(new String(output.toByteArray()));
> ResWrap<Entity> entityResWrap = DESERIALIZER.toEntity(new
> ByteArrayInputStream(output.toByteArray()));
> Property geometryCollection =
> entityResWrap.getPayload().getProperty("GeometryCollectionField");
> Assert.assertNotNull(geometryCollection);
> ValueType actualValueType = geometryCollection.getValueType();
> Assert.assertEquals("Unexpected GeospatialCollection type",
> ValueType.GEOSPATIAL, actualValueType);
> Assert.assertTrue(geometryCollection.asGeospatial() instanceof

> {code}
> Please, note that the deserializer works fine for GeometryPoint type.
