virtual |
Returns a list of features representing the calculated elevation results.
The default implementation returns an empty list.
Reimplemented in QgsAbstractProfileSurfaceResults, QgsPointCloudLayerProfileResults, and QgsVectorLayerProfileResults.
Definition at line 62 of file qgsabstractprofilegenerator.cpp.
|
pure virtual |
Returns a list of geometries representing the calculated elevation results.
Implemented in QgsAbstractProfileSurfaceResults, QgsPointCloudLayerProfileResults, and QgsVectorLayerProfileResults.
|
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.
