Member Function Documentation

◆ asGeometries()

virtual QVector< QgsGeometry > QgsAbstractProfileResults::asGeometries ( ) const

pure virtual

Returns a list of geometries representing the calculated elevation results.

Implemented in QgsAbstractProfileSurfaceResults, QgsPointCloudLayerProfileResults, and QgsVectorLayerProfileResults.

◆ copyPropertiesFromGenerator()

void QgsAbstractProfileResults::copyPropertiesFromGenerator ( const QgsAbstractProfileGenerator * generator )

virtual

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 in QgsAbstractProfileSurfaceResults, QgsPointCloudLayerProfileResults, and QgsVectorLayerProfileResults.

Definition at line 77 of file qgsabstractprofilegenerator.cpp.

◆ distanceToHeightMap()

virtual QMap< double, double > QgsAbstractProfileResults::distanceToHeightMap ( ) const

pure virtual

Returns the map of distance (chainage) to height.

Implemented in QgsAbstractProfileSurfaceResults, and QgsPointCloudLayerProfileResults.

◆ identify() [1/2]

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