Member Function Documentation

◆ asFeatures()

QVector< QgsAbstractProfileResults::Feature > QgsVectorLayerProfileResults::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 from QgsAbstractProfileSurfaceResults.

Definition at line 63 of file qgsvectorlayerprofilegenerator.cpp.

◆ asGeometries()

QVector< QgsGeometry > QgsVectorLayerProfileResults::asGeometries ( ) const

overridevirtual

Returns a list of geometries representing the calculated elevation results.

Reimplemented from QgsAbstractProfileSurfaceResults.

Definition at line 49 of file qgsvectorlayerprofilegenerator.cpp.

◆ copyPropertiesFromGenerator()

void QgsVectorLayerProfileResults::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.

Reimplemented from QgsAbstractProfileSurfaceResults.

Definition at line 653 of file qgsvectorlayerprofilegenerator.cpp.

◆ identify() [1/2]

QVector< QgsProfileIdentifyResults > QgsVectorLayerProfileResults::identify	(	const QgsDoubleRange &	distanceRange,
		const QgsDoubleRange &	elevationRange,
		const QgsProfileIdentifyContext &	context
	)

overridevirtual

Identify results visible within the specified ranges.

Reimplemented from QgsAbstractProfileResults.

Definition at line 92 of file qgsvectorlayerprofilegenerator.cpp.

◆ identify() [2/2]

QVector< QgsProfileIdentifyResults > QgsVectorLayerProfileResults::identify	(	const QgsProfilePoint &	point,
		const QgsProfileIdentifyContext &	context
	)
