Examples with Literal org.opengis.filter.expression.Literal used on opensource projects

Example 6 with Literal

use of org.opengis.filter.expression.Literal in project ddf by codice.

the class OpenSearchQueryTest method testBboxSpatialFilter.

@Test
public void testBboxSpatialFilter() throws Exception {
    String bboxCorners = "0,10,20,30";
    OpenSearchQuery query = new OpenSearchQuery(null, 0, 10, "relevance", "desc", 30000, FILTER_BUILDER);
    query.addBBoxSpatialFilter(bboxCorners);
    Filter filter = query.getFilter();
    // String filterXml = getFilterAsXml( filter );
    VerificationVisitor verificationVisitor = new VerificationVisitor();
    filter.accept(verificationVisitor, null);
    HashMap<String, FilterStatus> map = (HashMap<String, FilterStatus>) verificationVisitor.getMap();
    printFilterStatusMap(map);
    // List<Filter> filters = getFilters( map, ContainsImpl.class.getName() );
    List<Filter> filters = getFilters(map, IntersectsImpl.class.getName());
    assertEquals(1, filters.size());
    // ContainsImpl containsFilter = (ContainsImpl) filters.get( 0 );
    IntersectsImpl containsFilter = (IntersectsImpl) filters.get(0);
    // The geometric point is wrapped in a <Literal> element, so have to
    // get geometry expression as literal and then evaluate it to get the
    // geometry.
    // Example:
    // <ogc:Literal>org.geotools.geometry.jts.spatialschema.geometry.primitive.SurfaceImpl@64a7c45e</ogc:Literal>
    Literal literalWrapper = (Literal) containsFilter.getExpression2();
    // Luckily we know what type the geometry expression should be, so we can cast it
    SurfaceImpl bbox = (SurfaceImpl) literalWrapper.evaluate(null);
    String[] expectedCoords = bboxCorners.split(",");
    double[] lowerCornerCoords = bbox.getEnvelope().getLowerCorner().getCoordinate();
    LOGGER.debug("lowerCornerCoords:  [0] = {},   [1] = {}", lowerCornerCoords[0], lowerCornerCoords[1]);
    assertEquals(Double.parseDouble(expectedCoords[0]), lowerCornerCoords[0], DOUBLE_DELTA);
    assertEquals(Double.parseDouble(expectedCoords[1]), lowerCornerCoords[1], DOUBLE_DELTA);
    double[] upperCornerCoords = bbox.getEnvelope().getUpperCorner().getCoordinate();
    LOGGER.debug("upperCornerCoords:  [0] = {},   [1] = {}", upperCornerCoords[0], upperCornerCoords[1]);
    assertEquals(Double.parseDouble(expectedCoords[2]), upperCornerCoords[0], DOUBLE_DELTA);
    assertEquals(Double.parseDouble(expectedCoords[3]), upperCornerCoords[1], DOUBLE_DELTA);
