A parameter for processing algorithms that need a list of input vector layers for writing of vector tiles - this parameter provides processing framework's adapter for QList<QgsVectorTileWriter::Layer>.
A valid value for this parameter is a list (QVariantList), where each item is a map (QVariantMap) in this form: { 'layer': string or QgsMapLayer, // key-value pairs below are optional 'layerName': string, 'filterExpression': string, 'minZoom': int, 'maxZoom': int }
Static functions parametersAsLayers(), variantMapAsLayer(), layerAsVariantMap() provide conversion between QgsVectorTileWriter::Layer representation and QVariant representation.

overridevirtual |
Returns the parameter definition as a Python command which can be used within a Python Processing script.
The outputType argument specifies the desired output format for the Python string, i.e. the intended end use of the generated Python code.

|
overridevirtual |
Checks whether the specified input value is acceptable for the parameter.
Returns true
if the value can be accepted. The optional context parameter can be specified to allow a more stringent check to be performed, capable of checking for the presence of required layers and other factors within the context.
