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 208 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.

Definition at line 218 of file qgsprocessingparameters.h.

◆ 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.

◆ operator QVariant()

QgsProcessingOutputLayerDefinition::operator QVariant ( ) const
inline

Allows direct construction of QVariants.

Definition at line 294 of file qgsprocessingparameters.h.

◆ operator!=()

bool QgsProcessingOutputLayerDefinition::operator!= ( const QgsProcessingOutputLayerDefinition other) const

Definition at line 106 of file qgsprocessingparameters.cpp.

◆ operator==()

bool QgsProcessingOutputLayerDefinition::operator== ( const QgsProcessingOutputLayerDefinition other) const

Definition at line 100 of file qgsprocessingparameters.cpp.

◆ remappingDefinition()

QgsRemappingSinkDefinition QgsProcessingOutputLayerDefinition::remappingDefinition ( ) const
inline

Returns the output remapping definition, if useRemapping() is true.

QGIS 3.14

Definition at line 263 of file qgsprocessingparameters.h.

◆ setRemappingDefinition()

void QgsProcessingOutputLayerDefinition::setRemappingDefinition ( const QgsRemappingSinkDefinition definition)

Sets the remapping definition to use when adding features to the output layer.

Calling this method will set useRemapping() to true.

Definition at line 68 of file qgsprocessingparameters.cpp.

◆ 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.

◆ useRemapping()

bool QgsProcessingOutputLayerDefinition::useRemapping ( ) const
inline

Returns true if the output uses a remapping definition.

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 246 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 238 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 233 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 226 of file qgsprocessingparameters.h.
