C++ (Cpp) getInteriorRing Examples

Example #1

OGRBoolean OGRPolygon::Equal( OGRGeometry * poOther )

{
    OGRPolygon *poOPoly = (OGRPolygon *) poOther;

    if( poOther == this )
        return TRUE;
    
    if( poOther->getGeometryType() != getGeometryType() )
        return FALSE;

    if( getNumInteriorRings() != poOPoly->getNumInteriorRings() )
        return FALSE;

    if( !getExteriorRing()->Equal( poOPoly->getExteriorRing() ) )
        return FALSE;
    
    // we should eventually test the SRS.

    for( int iRing = 0; iRing < getNumInteriorRings(); iRing++ )
    {
        if( !getInteriorRing(iRing)->Equal(poOPoly->getInteriorRing(iRing)) )
            return FALSE;
    }

    return TRUE;
}
