%Docstring
A collection of utilities for working with parameters when running a processing algorithm.
Parameters are stored in a QVariantMap and referenced by a unique string key.
The QVariants in parameters are not usually accessed
directly, and instead the high level API provided through QgsProcessingParameters
parameterAsString(), parameterAsDouble() are used instead.
Parameters are evaluated using a provided QgsProcessingContext, allowing
the evaluation to understand available map layers and expression contexts
(for expression based parameters).

%Docstring
Evaluates the parameter with matching ``definition`` to a feature sink.
The ``fields``, ``geometryType`` and ``crs`` parameters dictate the properties
of the resulting feature sink.
Sinks will either be taken from ``context``'s active project, or created from external
providers and stored temporarily in the ``context``. The ``destinationIdentifier``
argument will be set to a string which can be used to retrieve the layer corresponding
to the sink, e.g. via calling QgsProcessingUtils.mapLayerFromString().

Evaluates the parameter with matching ``definition`` to a source vector layer file path of compatible format.
If the parameter is evaluated to an existing layer, and that layer is not of the format listed in the
``compatibleFormats`` argument, then the layer will first be exported to a compatible format
in a temporary location. The function will then return the path to that temporary file.
``compatibleFormats`` should consist entirely of lowercase file extensions, e.g. 'shp'.
The ``preferredFormat`` argument is used to specify to desired file extension to use when a temporary
layer export is required. This defaults to shapefiles, because shapefiles are the future (don't believe the geopackage hype!).
