示例1: visitor
bool
RectangleIntersects::intersects(const geom::Geometry& geom)
{
if (!rectEnv.intersects(geom.getEnvelopeInternal()))
return false;
// test envelope relationships
EnvelopeIntersectsVisitor visitor(rectEnv);
visitor.applyTo(geom);
if (visitor.intersects()) return true;
// test if any rectangle corner is contained in the target
ContainsPointVisitor ecpVisitor(rectangle);
ecpVisitor.applyTo(geom);
if (ecpVisitor.containsPoint())
return true;
// test if any lines intersect
LineIntersectsVisitor liVisitor(rectangle);
liVisitor.applyTo(geom);
if (liVisitor.intersects())
return true;
return false;
}示例2: visit
void visit(const geom::Geometry &geom)
{
using GEOMETRY::algorithm::locate::SimplePointInAreaLocator;
const geom::Polygon *poly;
if ( !(poly=dynamic_cast<const geom::Polygon *>(&geom)) ) {
return;
}
const geom::Envelope &elementEnv = *(geom.getEnvelopeInternal());
if ( !rectEnv.intersects(elementEnv) ) {
return;
}
// test each corner of rectangle for inclusion
for (int i=0; i<4; i++)
{
const geom::Coordinate &rectPt=rectSeq.getAt(i);
if ( !elementEnv.contains(rectPt) ) {
continue;
}
// check rect point in poly (rect is known not to
// touch polygon at this point)
if ( SimplePointInAreaLocator::containsPointInPolygon(rectPt, poly) )
{
containsPointVar=true;
return;
}
}
