◆ asFeatures()

QVector< QgsAbstractProfileResults::Feature > QgsAbstractProfileSurfaceResults::asFeatures	(	Qgis::ProfileExportType	type,
		QgsFeedback *	feedback = `nullptr`
	)		const

overridevirtual

Returns a list of features representing the calculated elevation results.

The default implementation returns an empty list.

Since: QGIS 3.32

Reimplemented in QgsVectorLayerProfileResults.

Definition at line 58 of file qgsabstractprofilesurfacegenerator.cpp.

◆ asGeometries()

QVector< QgsGeometry > QgsAbstractProfileSurfaceResults::asGeometries ( ) const

overridevirtual

Returns a list of geometries representing the calculated elevation results.

Implements QgsAbstractProfileResults.

◆ copyPropertiesFromGenerator()

void QgsAbstractProfileSurfaceResults::copyPropertiesFromGenerator ( const QgsAbstractProfileGenerator * generator )

overridevirtual

Copies properties from specified generator to the results object.

For instance, this method can be used to copy any properties relating to rendering the gathered results to reflect the generator's current properties.

The base class method does nothing.
