Examples with Geometry org.neo4j.graphdb.spatial.Geometry used on opensource projects

Example 1 with Geometry

use of org.neo4j.graphdb.spatial.Geometry in project neo4j by neo4j.

the class GraphDatabaseServiceExecuteTest method shouldBeAbleToUseExternalGeometryAsParameterToQuery.

@Test
public void shouldBeAbleToUseExternalGeometryAsParameterToQuery() throws Exception {
    // given a point created from public interface
    GraphDatabaseService graphDb = new TestGraphDatabaseFactory().newImpermanentDatabase();
    Geometry geometry = makeFakePointAsGeometry(144.317718, -37.031738, makeWGS84());
    // when passing as params to a distance function
    Result result = graphDb.execute("RETURN distance(point({longitude: 144.317718, latitude: -37.031738}),{previous}) AS dist", map("previous", geometry));
    // then
    Double dist = (Double) result.next().get("dist");
    assertThat(dist, equalTo(0.0));
}
