Examples with ValueGeometry org.h2.value.ValueGeometry used on opensource projects

Example 6 with ValueGeometry

use of org.h2.value.ValueGeometry in project h2database by h2database.

the class TestSpatial method testWKB.

/**
 * Test serialization of Z and SRID values.
 */
private void testWKB() {
    ValueGeometry geom3d = ValueGeometry.get("POLYGON ((67 13 6, 67 18 5, 59 18 4, 59 13 6,  67 13 6))", 27572);
    ValueGeometry copy = ValueGeometry.get(geom3d.getBytes());
    assertEquals(6, copy.getGeometry().getCoordinates()[0].z);
    assertEquals(5, copy.getGeometry().getCoordinates()[1].z);
    assertEquals(4, copy.getGeometry().getCoordinates()[2].z);
    // Test SRID
    copy = ValueGeometry.get(geom3d.getBytes());
    assertEquals(27572, copy.getGeometry().getSRID());
}

Example 7 with ValueGeometry

use of org.h2.value.ValueGeometry in project h2database by h2database.

the class TestSpatial method testEquals.

/**
 * Test equality method on ValueGeometry
 */
private void testEquals() {
    // 3d equality test
    ValueGeometry geom3d = ValueGeometry.get("POLYGON ((67 13 6, 67 18 5, 59 18 4, 59 13 6,  67 13 6))");
    ValueGeometry geom2d = ValueGeometry.get("POLYGON ((67 13, 67 18, 59 18, 59 13,  67 13))");
    assertFalse(geom3d.equals(geom2d));
    // SRID equality test
    GeometryFactory geometryFactory = new GeometryFactory();
    Geometry geometry = geometryFactory.createPoint(new Coordinate(0, 0));
    geometry.setSRID(27572);
    ValueGeometry valueGeometry = ValueGeometry.getFromGeometry(geometry);
    Geometry geometry2 = geometryFactory.createPoint(new Coordinate(0, 0));
    geometry2.setSRID(5326);
    ValueGeometry valueGeometry2 = ValueGeometry.getFromGeometry(geometry2);
    assertFalse(valueGeometry.equals(valueGeometry2));
    ValueGeometry valueGeometry3 = ValueGeometry.getFromGeometry(geometry);
    assertEquals(valueGeometry, valueGeometry3);
    assertEquals(geometry.getSRID(), valueGeometry3.getGeometry().getSRID());
    // Check illegal geometry (no WKB representation)
    try {
        ValueGeometry.get("POINT EMPTY");
        fail("expected this to throw IllegalArgumentException");
    } catch (IllegalArgumentException ex) {
    // expected
    }
}

Example 8 with ValueGeometry

use of org.h2.value.ValueGeometry in project ignite by apache.

the class GridH2SpatialIndex method findByGeometry.

/**
 * {@inheritDoc}
 */
@Override
public Cursor findByGeometry(TableFilter filter, SearchRow first, SearchRow last, SearchRow intersection) {
    Value v = intersection.getValue(columnIds[0]);
    Geometry g = ((ValueGeometry) v.convertTo(Value.GEOMETRY)).getGeometry();
    int seg = segmentsCount() == 1 ? 0 : H2Utils.context(filter.getSession()).segment();
    GridCursor<IndexRow> cursor = delegate.findByGeometry(seg, filter, g);
    GridCursor<H2Row> h2cursor = new IndexValueCursor<>(cursor, this::mapIndexRow);
    return new H2Cursor(h2cursor);
