Detailed Description

A collection of utilities for working with parameters when running a processing algorithm.

Parameters are stored in a QVariantMap and referenced by a unique string key. The QVariants in parameters are not usually accessed directly, and instead the high level API provided through QgsProcessingParameters parameterAsString(), parameterAsDouble() are used instead.

Parameters are evaluated using a provided QgsProcessingContext, allowing the evaluation to understand available map layers and expression contexts (for expression based parameters).

Member Function Documentation

◆ descriptionFromName()

QString QgsProcessingParameters::descriptionFromName ( const QString & name )

static

Creates an autogenerated parameter description from a parameter name.

◆ isDynamic()

◆ parameterAsAnnotationLayer() [1/2]

QgsAnnotationLayer * QgsProcessingParameters::parameterAsAnnotationLayer	(	const QgsProcessingParameterDefinition *	definition,
		const QVariant &	value,
		QgsProcessingContext &	context
	)

static

Evaluates the parameter with matching definition and value to an annotation layer.

Layers will be taken from context's active project. Callers do not need to handle deletion of the returned layer.

Warning: Working with annotation layers is generally not thread safe (unless the layers are from a QgsProject loaded directly in a background thread). Ensure your algorithm returns the QgsProcessingAlgorithm::FlagNoThreading flag or only accesses annotation layers from a prepareAlgorithm() or postProcessAlgorithm() step.

Since: QGIS 3.10

Definition at line 2096 of file qgsprocessingparameters.cpp.

◆ parameterAsCompatibleSourceLayerPath()

QString QgsProcessingParameters::parameterAsCompatibleSourceLayerPath	(	const QgsProcessingParameterDefinition *	definition,
		const QVariantMap &	parameters,
		QgsProcessingContext &	context,
		const QStringList &	compatibleFormats,
		const QString &	preferredFormat = `QString( "shp" )`,
		QgsProcessingFeedback *	feedback = `nullptr`
	)

static

Evaluates the parameter with matching definition to a source vector layer file path of compatible format.

If the parameter is evaluated to an existing layer, and that layer is not of the format listed in the compatibleFormats argument, then the layer will first be exported to a compatible format in a temporary location. The function will then return the path to that temporary file.

compatibleFormats should consist entirely of lowercase file extensions, e.g. 'shp'.

The preferredFormat argument is used to specify to desired file extension to use when a temporary layer export is required. This defaults to shapefiles, because shapefiles are the future (don't believe the geopackage hype!).

When an algorithm is capable of handling multi-layer input files (such as Geopackage), it is preferable to use parameterAsCompatibleSourceLayerPathAndLayerName() which may avoid conversion in more situations.

Definition at line 836 of file qgsprocessingparameters.cpp.

◆ parameterAsCompatibleSourceLayerPathAndLayerName()

QString QgsProcessingParameters::parameterAsCompatibleSourceLayerPathAndLayerName	(	const QgsProcessingParameterDefinition *	definition,
		const QVariantMap &	parameters,
		QgsProcessingContext &	context,
		const QStringList &	compatibleFormats,
		const QString &	preferredFormat = `QString( "shp" )`,
		QgsProcessingFeedback *	feedback = `nullptr`,
		QString *	layerName = `nullptr`
	)

static

Evaluates the parameter with matching definition to a source vector layer file path and layer name of compatible format.

If the parameter is evaluated to an existing layer, and that layer is not of the format listed in the compatibleFormats argument, then the layer will first be exported to a compatible format in a temporary location. The function will then return the path to that temporary file.

compatibleFormats should consist entirely of lowercase file extensions, e.g. 'shp'.

The preferredFormat argument is used to specify to desired file extension to use when a temporary layer export is required. This defaults to shapefiles, because shapefiles are the future (don't believe the geopackage hype!).

This method should be preferred over parameterAsCompatibleSourceLayerPath() when an algorithm is able to correctly handle files with multiple layers. Unlike parameterAsCompatibleSourceLayerPath(), it will not force a conversion in this case and will return the target layer name in the layerName argument.

Parameters

definition	associated parameter definition
parameters	input parameter value map
context	processing context
compatibleFormats	a list of lowercase file extensions compatible with the algorithm
preferredFormat	preferred format extension to use if conversion if required
feedback	feedback object
layerName	will be set to the target layer name for multi-layer sources (e.g. Geopackage)

Returns: path to source layer, or nearly converted compatible layer

		QgsProcessingContext &	context
	)

static

Evaluates the parameter with matching definition and value to a raster layer.

Layers will either be taken from context's active project, or loaded from external sources and stored temporarily in the context. In either case, callers do not need to handle deletion of the returned layer.

		const QVariantMap &	createOptions = `QVariantMap()`,
		const QStringList &	datasourceOptions = `QStringList()`,
		const QStringList &	layerOptions = `QStringList()`
	)

static

Evaluates the parameter with matching definition and value to a feature sink.

The fields, geometryType and crs parameters dictate the properties of the resulting feature sink.

Sinks will either be taken from context's active project, or created from external providers and stored temporarily in the context. The destinationIdentifier argument will be set to a string which can be used to retrieve the layer corresponding to the sink, e.g. via calling QgsProcessingUtils::mapLayerFromString().

The createOptions argument is used to pass on creation options such as layer name.

The datasourceOptions and layerOptions arguments is used to pass on GDAL-specific format driver options.

This function creates a new object and the caller takes responsibility for deleting the returned object.
