Member Function Documentation

◆ feedback()

QgsFeedback * QgsVectorLayerProfileGenerator::feedback ( ) const
overridevirtual

Access to feedback object of the generator (may be nullptr)

Implements QgsAbstractProfileGenerator.

Definition at line 800 of file qgsvectorlayerprofilegenerator.cpp.

◆ generateProfile()

bool QgsVectorLayerProfileGenerator::generateProfile ( const QgsProfileGenerationContext context = QgsProfileGenerationContext())
overridevirtual

Generate the profile (based on data stored in the class).

Returns true if the profile was generated successfully (i.e. the generation was not canceled early).

Implements QgsAbstractProfileGenerator.

Definition at line 718 of file qgsvectorlayerprofilegenerator.cpp.

◆ sourceId()

QString QgsVectorLayerProfileGenerator::sourceId ( ) const
overridevirtual

Returns a unique identifier representing the source of the profile.

For generators associated with a map layer the source ID will match the layer's QgsMapLayer::id(). Other (non-map-layer) sources will have a different unique ID with its own custom interpretation.gen

Implements QgsAbstractProfileGenerator.

Definition at line 711 of file qgsvectorlayerprofilegenerator.cpp.

◆ takeResults()

QgsAbstractProfileResults * QgsVectorLayerProfileGenerator::takeResults ( )
overridevirtual

Takes results from the generator.

Ownership is transferred to the caller.

Implements QgsAbstractProfileGenerator.

Definition at line 795 of file qgsvectorlayerprofilegenerator.cpp.
