Abstract base class for individual validity checks.
virtual bool prepareCheck(const QgsValidityCheckContext *context, QgsFeedback *feedback)
Prepares the check for execution, and returns true if the check can be run.
virtual QString id() const =0
Returns the unique ID of the check.
virtual int checkType() const =0
Returns the type of the check.
virtual QgsAbstractValidityCheck * create() const =0
Creates a new instance of the check and returns it.
virtual QList< QgsValidityCheckResult > runCheck(const QgsValidityCheckContext *context, QgsFeedback *feedback)=0
Runs the check and returns a list of results.
virtual ~QgsAbstractValidityCheck()=default
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition qgsfeedback.h:44
Base class for validity check contexts.
Represents an individual result from a validity check run by a QgsAbstractValidityCheck subclass.
@ Critical
Critical error - notify user of result and prevent operation from proceeding.
@ Warning
Warning only, allow operation to proceed but notify user of result.
QString checkId
ID of the check which generated the result.
QString detailedDescription
Detailed description of the result (translated), giving users enough detail for them to resolve the e...
QString title
A short, translated string summarising the result.
