Examples with GeometryCollection com.mongodb.client.model.geojson.GeometryCollection used on opensource projects

Example 1 with GeometryCollection

use of com.mongodb.client.model.geojson.GeometryCollection in project mongo-java-driver by mongodb.

the class GeometryDecoderHelper method decodeGeometryCollection.

private static GeometryCollection decodeGeometryCollection(final BsonReader reader) {
    String type = null;
    List<? extends Geometry> geometries = null;
    CoordinateReferenceSystem crs = null;
    reader.readStartDocument();
    while (reader.readBsonType() != BsonType.END_OF_DOCUMENT) {
        String key = reader.readName();
        if (key.equals("type")) {
            type = reader.readString();
        } else if (key.equals("geometries")) {
            geometries = decodeGeometries(reader);
        } else if (key.equals("crs")) {
            crs = decodeCoordinateReferenceSystem(reader);
        } else {
            throw new CodecConfigurationException(format("Unexpected key '%s' found when decoding a GeoJSON Polygon", key));
        }
    }
    reader.readEndDocument();
    if (type == null) {
        throw new CodecConfigurationException("Invalid GeometryCollection, document contained no type information.");
    } else if (!type.equals("GeometryCollection")) {
        throw new CodecConfigurationException(format("Invalid GeometryCollection, found type '%s'.", type));
    } else if (geometries == null) {
        throw new CodecConfigurationException("Invalid GeometryCollection, missing geometries.");
    }
    return crs != null ? new GeometryCollection(crs, geometries) : new GeometryCollection(geometries);
}

Example 2 with GeometryCollection

use of com.mongodb.client.model.geojson.GeometryCollection in project mongo-java-driver by mongodb.

the class GeometryEncoderHelper method encodeGeometry.

@SuppressWarnings("unchecked")
static void encodeGeometry(final BsonWriter writer, final Geometry value, final EncoderContext encoderContext, final CodecRegistry registry) {
    writer.writeStartDocument();
    writer.writeString("type", value.getType().getTypeName());
    if (value instanceof GeometryCollection) {
        writer.writeName("geometries");
        encodeGeometryCollection(writer, (GeometryCollection) value, encoderContext, registry);
    } else {
        writer.writeName("coordinates");
        if (value instanceof Point) {
            encodePoint(writer, (Point) value);
        } else if (value instanceof MultiPoint) {
            encodeMultiPoint(writer, (MultiPoint) value);
        } else if (value instanceof Polygon) {
            encodePolygon(writer, (Polygon) value);
        } else if (value instanceof MultiPolygon) {
            encodeMultiPolygon(writer, (MultiPolygon) value);
        } else if (value instanceof LineString) {
            encodeLineString(writer, (LineString) value);
        } else if (value instanceof MultiLineString) {
            encodeMultiLineString(writer, (MultiLineString) value);
        } else {
            throw new CodecConfigurationException(format("Unsupported Geometry: %s", value));
        }
    }
    encodeCoordinateReferenceSystem(writer, value, encoderContext, registry);
    writer.writeEndDocument();
