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.
Reimplemented from QgsProcessingParameterDefinition.
Definition at line 2983 of file qgsprocessingparameters.cpp.
|
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.
