Access processing results: extra tools

Description

A qgis_result object is a list that, next to the output elements, also contains other elements that can be useful in scripting. Several of these can be extracted with convenience functions: the exit status of the process, standard output and standard error of 'qgis_process', arguments passed to 'qgis_process'.

Usage

qgis_result_status(x)

qgis_result_stdout(x)

qgis_result_stderr(x)

qgis_result_args(x)

Arguments

x	A qgis_result object returned by qgis_run_algorithm().

Value

• A number in case of qgis_result_status().

• A string in case of qgis_result_stdout() and qgis_result_stderr().

• A list in case of qgis_result_args().
