Detailed Description

Checks if geometries are valid using the backend configured in the QGIS settings.

This does not offer any fixes but makes sure that all geometries are valid.

Constructor & Destructor Documentation

◆ QgsGeometryIsValidCheck()

QgsGeometryIsValidCheck::QgsGeometryIsValidCheck ( const QgsGeometryCheckContext context,
const QVariantMap &  configuration 
)
explicit

Creates a new is valid check with the provided context.

No options are supported in configuration.
