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.

overridevirtual |
Returns a version of the parameter input value, which is suitable for use in a JSON object.
This method must return only simple values which can be losslessly encapsulated in a serialized JSON map. For instance, any QGIS class values (such as QgsCoordinateReferenceSystem) must be converted to a simple string or numeric value equivalent.
