Qgs3DAlgorithms::Qgs3DAlgorithms | ( | QObject * | parent = nullptr | ) |
Constructor for Qgs3DAlgorithms.
|
overridevirtual |
Returns the provider help id string, used for creating QgsHelp urls for algorithms belong to this provider.
By default, this returns an empty string, meaning that no QgsHelp url should be created for the provider's algorithms.
Reimplemented from QgsProcessingProvider.

overridevirtual |
|
overridevirtual |
Returns the unique provider id, used for identifying the provider.
This string should be a unique, short, character only string, eg "qgis" or "gdal". This string should not be localised.
Implements QgsProcessingProvider.
|
overrideprotectedvirtual |
Loads all algorithms belonging to this provider.
Subclasses should implement this, calling addAlgorithm() to register all their associated algorithms.
Implements QgsProcessingProvider.
|
overridevirtual |
Returns the provider name, which is used to describe the provider within the GUI.
This string should be short (e.g. "Lastools") and localised.
Implements QgsProcessingProvider.
|
overridevirtual |
Returns true
if the provider supports non-file based outputs (such as memory layers or direct database outputs).
If a provider returns false
for this method than it indicates that none of the outputs from any of the provider's algorithms have support for non-file based outputs. Returning true
indicates that the algorithm's parameters will each individually declare their non-file based support.
The default behavior for providers is to support non-file based outputs, and most providers which rely solely on QGIS API (and which do not depend on third-party scripts or external dependencies) will automatically support this.

overridevirtual |
Returns a path to an SVG version of the provider's icon.
