Member Function Documentation

◆ feedback()

QgsFeedback * QgsTriangulatedPointCloudLayerProfileGenerator::feedback ( ) const

overridevirtual

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

Implements QgsAbstractProfileGenerator.

Definition at line 1048 of file qgspointcloudlayerprofilegenerator.cpp.

◆ generateProfile()

bool QgsTriangulatedPointCloudLayerProfileGenerator::generateProfile ( const QgsProfileGenerationContext & context )

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 922 of file qgspointcloudlayerprofilegenerator.cpp.

◆ sourceId()

QString QgsTriangulatedPointCloudLayerProfileGenerator::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 910 of file qgspointcloudlayerprofilegenerator.cpp.

◆ takeResults()

QgsAbstractProfileResults * QgsTriangulatedPointCloudLayerProfileGenerator::takeResults ( )

overridevirtual

Takes results from the generator.

Ownership is transferred to the caller.

Implements QgsAbstractProfileGenerator.

Definition at line 1043 of file qgspointcloudlayerprofilegenerator.cpp.

◆ type()

QString QgsTriangulatedPointCloudLayerProfileGenerator::type ( ) const

overridevirtual

Returns the unique string identifier for the results type.

Implements QgsAbstractProfileGenerator.

Definition at line 915 of file qgspointcloudlayerprofilegenerator.cpp.
