Detailed Description

A topology check for missing vertices.

Any vertex which is on the border of another polygon but no corresponding vertex can be found on the other polygon will be reported as an error.

Since
QGIS 3.4

Definition at line 87 of file qgsgeometrymissingvertexcheck.h.

Member Enumeration Documentation

◆ ResolutionMethod

◆ checkType()

QgsGeometryCheck::CheckType QgsGeometryMissingVertexCheck::checkType ( ) const
overridevirtual

Returns the check type.
