any way to distinguish between an outer loop and an inner loop of AcdbHatch?

It seems that there is no extral information to distinguish between an outer loop and an inner loop of AcdbHatch.

AcdbHathc::

getLoopAt(

int loopIndex,

Adesk::Int32& loopType,

AcGeVoidPointerArray& edgePtrs,

AcGeIntArray& edgeTypes) const;

the param "loopType" can tell types like kDefault, kExternal, kPolyline, kDerived, kTextbox.

KExternal means an outer loop, do all the others types mean inner loops?

Dose AcdbHatch have some function like AcDbMPolygon::

getLoopDirection(

int lindex,

AcDbMPolygon::loopDir& dir) const;

dir can be

kExterior	0	Loop direction is counter-clockwise.
kInterior		Loop direction is clockwise.
kAnnotation		Text.
