QgsProcessingParameterFeatureSink
¶ Bases:
qgis._core.QgsProcessingDestinationParameter
A feature sink output for processing algorithms.
A parameter which represents the destination feature sink for features created by an algorithm.
New in version 3.0: Methods
algorithm
Returns a pointer to the algorithm which owns this parameter. asScriptCode
checkValueIsAcceptable
clone
createByDefault
Returns true if the destination should be created by default. dataType
Returns the layer type for sinks associated with the parameter. defaultFileExtension
defaultValue
Returns the default value for the parameter. dependsOnOtherParameters
Returns a list of other parameter names on which this parameter is dependent (e.g. description
Returns the description for the parameter. dynamicLayerParameterName
Returns the name of the parameter for a layer linked to a dynamic parameter, or an empty string if this is not set. dynamicPropertyDefinition
Returns the property definition for dynamic properties. flags
Returns any flags associated with the parameter. fromScriptCode
Creates a new parameter using the definition from a script code. fromVariantMap
generateTemporaryDestination
hasGeometry
Returns true if sink is likely to include geometries. isDestination
isDynamic
Returns true if the parameter supports is dynamic, and can support data-defined values (i.e. metadata
Returns the parameter’s freeform metadata. name
Returns the name of the parameter. provider
Returns a pointer to the provider for the algorithm which owns this parameter. setCreateByDefault
Sets whether the destination should be created by default. setDataType
Sets the layer type
for the sinks associated with the parameter.setDefaultValue
Sets the default value
for the parameter.setDescription
Sets the description
for the parameter.setDynamicLayerParameterName
Sets the name
for the parameter for a layer linked to a dynamic parameter, or an empty string if this is not set.setDynamicPropertyDefinition
Sets the property definition
for dynamic properties.setFlags
Sets the flags
associated with the parameter.setIsDynamic
Sets whether the parameter is dynamic
, and can support data-defined values (i.e.setMetadata
Sets the parameter’s freeform metadata
.setName
Sets the name
of the parameter.setSupportsNonFileBasedOutputs
Sets whether the destination parameter supports non filed-based outputs, such as memory layers or direct database outputs. supportsNonFileBasedOutputs
Returns true if the destination parameter supports non filed-based outputs, such as memory layers or direct database outputs. toOutputDefinition
toVariantMap
toolTip
Returns a formatted tooltip for use with the parameter, which gives helpful information like parameter description, ID, and extra content like default values (depending on parameter type). type
typeName
Returns the type name for the parameter class. valueAsPythonString
