示例1: if
IntersectResult PolygonContainer<TYPE>::QueryPointInPolygon(Node* node)
{
QuadTree* tree = this;
while(tree)
{
if(tree == 0) continue;
QuadObjects objects = tree->GetObjects();
QuadObjectIterator it = objects.begin();
for(;it != objects.end();it++)
{
QuadObject* quad = *it;
TYPE* poly = (TYPE*)quad;
IntersectResult ret = PointInPolygon(node, poly);
if (ret != IR_SEPERATE) return ret;
