Example 1 with AttributeIF

use of com.runwaysdk.dataaccess.AttributeIF in project geoprism-registry by terraframe.

the class VectorTileBuilder method writeVectorTiles.

protected byte[] writeVectorTiles(String layerName, Envelope envelope, ValueQuery query) throws IOException {
    OIterator<ValueObject> iterator = query.getIterator();
    try {
        List<Geometry> geometries = new LinkedList<Geometry>();
        while (iterator.hasNext()) {
            ValueObject object = iterator.next();
            AttributeGeometryIF attributeIF = (AttributeGeometryIF) object.getAttributeIF(GeoserverFacade.GEOM_COLUMN);
            Geometry geometry = attributeIF.getGeometry();
            geometry.setUserData(this.getUserData(object));
            geometries.add(geometry);
        }
        GeometryFactory geomFactory = new GeometryFactory();
        IGeometryFilter acceptAllGeomFilter = geometry -> true;
        MvtLayerParams layerParams = new MvtLayerParams();
        TileGeomResult tileGeom = JtsAdapter.createTileGeom(geometries, envelope, geomFactory, layerParams, acceptAllGeomFilter);
        final VectorTile.Tile.Builder tileBuilder = VectorTile.Tile.newBuilder();
        // Create MVT layer
        final MvtLayerProps layerProps = new MvtLayerProps();
        final IUserDataConverter ignoreUserData = new UserDataConverter();
        // MVT tile geometry to MVT features
        final List<VectorTile.Tile.Feature> features = JtsAdapter.toFeatures(tileGeom.mvtGeoms, layerProps, ignoreUserData);
        final VectorTile.Tile.Layer.Builder layerBuilder = MvtLayerBuild.newLayerBuilder(layerName, layerParams);
        layerBuilder.addAllFeatures(features);
        MvtLayerBuild.writeProps(layerBuilder, layerProps);
        // Build MVT layer
        final VectorTile.Tile.Layer layer = layerBuilder.build();
        // Add built layer to MVT
        tileBuilder.addLayers(layer);
        // / Build MVT
        Tile mvt = tileBuilder.build();
        return mvt.toByteArray();
    } finally {
        iterator.close();
    }
}

Example 2 with AttributeIF

use of com.runwaysdk.dataaccess.AttributeIF in project geoprism-registry by terraframe.

the class VectorTileBuilder method getUserData.

protected Map<String, String> getUserData(ValueObject object) {
    AttributeIF[] attributes = object.getAttributeArrayIF();
    Map<String, String> data = new TreeMap<String, String>();
    for (AttributeIF attribute : attributes) {
        String name = attribute.getName();
        if (!name.equals(GeoserverFacade.GEOM_COLUMN)) {
            data.put(name, attribute.getValue());
        }
    }
    return data;
}
