Class: QgsProcessingParameterNumber¶

class qgis.core.QgsProcessingParameterNumber¶

Bases: qgis._core.QgsProcessingParameterDefinition

A numeric parameter for processing algorithms.

New in version 3.0: Methods

`algorithm`	Returns a pointer to the algorithm which owns this parameter.
`asScriptCode`	Returns the parameter definition encoded in a string which can be used within a Python processing script.
`checkValueIsAcceptable`
`clone`
`dataType`	Returns the acceptable data type for the parameter.
`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`
`isDestination`	Returns true if this parameter represents a file or layer destination, e.g.
`isDynamic`	Returns true if the parameter supports is dynamic, and can support data-defined values (i.e.
`maximum`	Returns the maximum value acceptable by the parameter.
`metadata`	Returns the parameter’s freeform metadata.
`minimum`	Returns the minimum value acceptable by the parameter.
`name`	Returns the name of the parameter.
`provider`	Returns a pointer to the provider for the algorithm which owns this parameter.
`setDataType`	Sets the acceptable data `type` for 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.
`setMaximum`	Sets the `maximum` value acceptable by the parameter.
`setMetadata`	Sets the parameter’s freeform `metadata`.
`setMinimum`	Sets the `minimum` value acceptable by the parameter.
`setName`	Sets the `name` of the parameter.
`toVariantMap`
`toolTip`
`type`
`typeName`	Returns the type name for the parameter class.
