set不是boost :: PolygonSet的成员
我正在尝试为PolygonSet重载＆运算符，但以下列错误结束。 我可以理解boost :: PolygonSet没有设置功能，但任何人都可以提供我解决此问题的输入。 我尝试过view_as，但没有成功。
代码：
Function definition for concept
namespace boost { namespace polygon {
template <>
struct geometry_concept<boost_geom_api::PolygonSet> {
typedef polygon_set_concept type;
}; } }
PolygonSet PolygonSet::operator&(const PolygonSet& right) const {
using namespace boost::polygon::operators;
PolygonSet ps (*this);
ps &= right;
return ps;
}
PolygonSet& PolygonSet::operator&=(const PolygonSet& right) {
using namespace boost::polygon::operators;
using namespace gtl;
pgns &= right.pgns;
return (*this); }
错误 ：
