Member Enumeration Documentation

enum SFCGAL::algorithm::EqualityStrictness::Flag

Binary enum to define what is allowed when comparing geometries.

Exclusions:

• can not have CheckCoverOrPoint and any of InternalPoint* checks
• can not have multiple InternalPoint* checks

Enumerator
CheckCoverOrPoint	kind of check: point or cover. 1 is cover, 0 is point
SubGeomOrdered	sub geometries need to be ordered
SubPartOrdered	sub parts need to be ordered
InternalPointOrdered	sub geometry points need to be ordered, no shifted is allowed
InternalPointShifted	sub geometry points need to be ordered but shifted is allowed
InternalPointInverted	sub geometry points need to be ordered but inverted sequence is allowed
