Postprocessing validation

The postExecute method is an optional validation method that runs after a tool's processing is complete. The method is called after a tool's script file is complete and the outputs are added to the Contents pane for the active map. This method allows you to use the module to query and change the display of outputs.

The postExecute code identifies the layer from the active map and uses a SimpleRenderer value to change the symbology for each point to an airport symbol. The code assumes that the tool's second parameter is an output point feature class.

def postExecute(self):
        project ='CURRENT')
        active_map = project.activeMap
        if active_map:
            out_layer = active_map.listLayers(os.path.basename(self.params[1].valueAsText))[0]
            symbology = out_layer.symbology
            symbology.renderer.symbol.size = 12
            out_layer.symbology = symbology
