Member Function Documentation

feedback()

QgsFeedback * QgsRasterLayerProfileGenerator::feedback ( ) const

overridevirtual

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

Implements QgsAbstractProfileGenerator.

Definition at line 380 of file qgsrasterlayerprofilegenerator.cpp.

flags()

Qgis::ProfileGeneratorFlags QgsRasterLayerProfileGenerator::flags ( ) const

overridevirtual

Returns flags which reflect how the profile generator operates.

Reimplemented from QgsAbstractProfileGenerator.

Definition at line 92 of file qgsrasterlayerprofilegenerator.cpp.

generateProfile()

bool QgsRasterLayerProfileGenerator::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 99 of file qgsrasterlayerprofilegenerator.cpp.

sourceId()

QString QgsRasterLayerProfileGenerator::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 87 of file qgsrasterlayerprofilegenerator.cpp.

takeResults()

QgsAbstractProfileResults * QgsRasterLayerProfileGenerator::takeResults ( )

overridevirtual

Takes results from the generator.

Ownership is transferred to the caller.

Implements QgsAbstractProfileGenerator.

Definition at line 375 of file qgsrasterlayerprofilegenerator.cpp.
