Constructor & Destructor Documentation

QgsProcessingOutputLayerDefinition() [1/2]

QgsProcessingOutputLayerDefinition::QgsProcessingOutputLayerDefinition ( const QString &  sink = QString(), QgsProject *  destinationProject = nullptr  )

inline

Constructor for QgsProcessingOutputLayerDefinition, accepting a static sink/layer string.

The destinationProject parameter can be set to a QgsProject instance in which to automatically load the resulting sink/layer after completing processing.

Definition at line 211 of file qgsprocessingparameters.h.

QgsProcessingOutputLayerDefinition() [2/2]

QgsProcessingOutputLayerDefinition::QgsProcessingOutputLayerDefinition ( const QgsProperty &  sink, QgsProject *  destinationProject = nullptr  )

inline

Constructor for QgsProcessingOutputLayerDefinition, accepting a QgsProperty sink/layer.

The destinationProject parameter can be set to a QgsProject instance in which to automatically load the resulting sink/layer after completing processing.

loadVariant()

bool QgsProcessingOutputLayerDefinition::loadVariant

(

const QVariantMap &

map

)

Loads this output layer definition from a QVariantMap, wrapped in a QVariant.

You can use QgsXmlUtils::readVariant to load it from an XML document.

setRemappingDefinition()

void QgsProcessingOutputLayerDefinition::setRemappingDefinition

(

const QgsRemappingSinkDefinition &

definition

toVariant()

QVariant QgsProcessingOutputLayerDefinition::toVariant

(

)

const

Saves this output layer definition to a QVariantMap, wrapped in a QVariant.

You can use QgsXmlUtils::writeVariant to save it to an XML document.

Member Data Documentation

createOptions

QVariantMap QgsProcessingOutputLayerDefinition::createOptions

Map of optional sink/layer creation options, which are passed to the underlying provider when creating new layers.

Known options also include 'fileEncoding', which is used to specify a file encoding to use for created files.

Definition at line 249 of file qgsprocessingparameters.h.

destinationName

QString QgsProcessingOutputLayerDefinition::destinationName

Name to use for sink if it's to be loaded into a destination project.

Definition at line 241 of file qgsprocessingparameters.h.

destinationProject

QgsProject* QgsProcessingOutputLayerDefinition::destinationProject = nullptr

Destination project.

Can be set to a QgsProject instance in which to automatically load the resulting sink/layer after completing processing. The default behavior is not to load the result into any project (nullptr).

Definition at line 236 of file qgsprocessingparameters.h.

sink

QgsProperty QgsProcessingOutputLayerDefinition::sink

Sink/layer definition.

Usually a static property set to the destination file name for the sink's layer.

Definition at line 229 of file qgsprocessingparameters.h.
