ProcessingModelChildParameterSource
Processing model child parameter sources.
@ ExpressionText
Parameter value is taken from a text with expressions, evaluated just before the algorithm runs.
@ ModelOutput
Parameter value is linked to an output parameter for the model.
@ ChildOutput
Parameter value is taken from an output generated by a child algorithm.
@ ModelParameter
Parameter value is taken from a parent model parameter.
@ StaticValue
Parameter value is a static value.
@ Expression
Parameter value is taken from an expression, evaluated just before the algorithm runs.
Contains information about the context in which a processing algorithm is executed.
Base class for the definition of processing parameters.
