Methods

format

Returns the format (if set)

loadVariant

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

remappingDefinition

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

setFormat

Sets the format of the output dataset

setRemappingDefinition

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

toVariant

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

useRemapping

Returns True if the output uses a remapping definition.

class qgis.core.QgsProcessingOutputLayerDefinition[source]

Bases: object

__init__(sink: str | None = '', destinationProject: QgsProject | None = None)

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.

Parameters:
__init__(sink: QgsProperty, destinationProject: QgsProject | None = None)

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.

Parameters:
__init__(a0: QgsProcessingOutputLayerDefinition)
Parameters:

a0 (QgsProcessingOutputLayerDefinition)

createOptions: Dict[str, object]
destinationName: str
destinationProject: QgsProject
format(self) → str[source]

Returns the format (if set)

Return type:

str

loadVariant(self, map: dict[str | None, Any]) → bool[source]

Loads this output layer definition from a QVariantMap, wrapped in a QVariant. You can use QgsXmlUtils.readVariant to load it from an XML document.

Added in version 3.2.

Parameters:

map (dict[Optional[str], Any])

Return type:

bool

remappingDefinition(self) → QgsRemappingSinkDefinition[source]

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

setRemappingDefinition()

Added in version 3.14.

Return type:

QgsRemappingSinkDefinition

setFormat(self, format: str | None)[source]

Sets the format of the output dataset

format()

Added in version 4.0.

Parameters:

format (Optional[str])

setRemappingDefinition(self, definition: QgsRemappingSinkDefinition)[source]

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

Calling this method will set useRemapping() to True.
