A feature pool is based on a vector layer and caches features.
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition: qgsfeedback.h:45
Base configuration for geometry checks.
This represents an error reported by a geometry check.
This class implements a geometry check.
Manages and runs a set of geometry checks.
