示例1: coord
void object::test<10>()
{
geos::geom::Coordinate coord(x_, y_, z_);
CoordArrayPtr sequence = new geos::geom::CoordinateArraySequence();
ensure( "sequence is null pointer.", sequence != 0 );
sequence->add(coord);
PointPtr pt = factory_.createPoint(sequence);
ensure( "createPoint() returned null pointer.", pt != 0 );
ensure( "createPoint() returned empty point.", !pt->isEmpty() );
ensure( pt->isSimple() );
ensure( pt->isValid() );
ensure( pt->getCoordinate() != 0 );
CoordinateCPtr pcoord = pt->getCoordinate();
ensure( pcoord != 0 );
ensure_equals( pcoord->x, x_ );
ensure_equals( pcoord->y, y_ );
ensure_equals( pcoord->z, z_ );
GeometryPtr geo = 0;
geo = pt->getEnvelope();
ensure( geo != 0 );
ensure( !geo->isEmpty() );
factory_.destroyGeometry(geo);
geo = pt->getCentroid();
ensure( geo != 0 );
ensure( !geo->isEmpty() );
factory_.destroyGeometry(geo);
geo = pt->getBoundary();
ensure( geo != 0 );

ensure( geo != 0 );
ensure( !geo->isEmpty() );
factory_.destroyGeometry(geo);
ensure_equals( pt->getGeometryTypeId(), geos::geom::GEOS_POINT );
ensure_equals( pt->getDimension(), geos::geom::Dimension::P );

ensure_equals( pt->getNumPoints(), 1u );
ensure_equals( pt->getLength(), 0.0 );

// FREE MEMORY
factory_.destroyGeometry(pt);
