Base class for providing feedback from a processing algorithm.
QList< QgsFeature > QgsFeatureList
A geometry is the spatial representation of a feature.
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
bool hasGeometry() const
Returns true if the feature has an associated geometry.
QgsGeometry mergeLines() const
Merges any connected lines in a LineString/MultiLineString geometry and converts them to single line ...
Type
The WKB type describes the number of dimensions a geometry has.
QgsGeometry geometry() const
Returns the geometry associated with this feature.
void setGeometry(const QgsGeometry &geometry)
Set the feature's geometry.
SourceType
Data source types enum.
Contains information about the context in which a processing algorithm is executed.
virtual void reportError(const QString &error, bool fatalError=false)
Reports that the algorithm encountered an error while executing.
