is odgeray2d instanciable?
is odgeray2d instanciable?
i get a compile-time error when i try to use odgeray2d:
c:\dev\floor2\fdxfio.cpp(771) : error c2259: 'odgeray2d' : cannot instantiate abstract class due to following members:
c:\dev\dwgdirect1.10\include\ge\geray2d.h(34) : see declaration of 'odgeray2d'
c:\dev\floor2\fdxfio.cpp(771) : warning c4259: 'bool __thiscall odgecurve2d::hasstartpoint(class odgepoint2d &) const' : pure virtual function was not defined
c:\dev\dwgdirect1.10\include\ge\gecurve2d.h(143) : see declaration of 'hasstartpoint'
c:\dev\floor2\fdxfio.cpp(771) : warning c4259: 'bool __thiscall odgecurve2d::hasendpoint(class odgepoint2d &) const' : pure virtual function was not defined
c:\dev\dwgdirect1.10\include\ge\gecurve2d.h(144) : see declaration of 'hasendpoint'
isn't odgeray2d meant for direct use?
thanks,
