After playing around with the Model Builder and looking at the python scripts of what I make, I noticed some syntax which I can't find the definition anywhere. Here is a snippet of the python script from a model:
outputs_13=processing.runalg("qgis:fieldcalculator", outputs_12['SAVENAME'], ID, 1, 10, 0, True, $rownum , None) outputs_14=processing.runalg("qgis:deletecolumn", outputs_13['OUTPUT_LAYER'], longitude, None) outputs_15=processing.runalg("qgis:deletecolumn", outputs_14['SAVENAME'], latitude, savename_alg15) outputs_16=processing.runalg("qgis:clip", outputs_15['SAVENAME'], vectorlayer_layer1, None) outputs_17=processing.runalg("qgis:fieldcalculator", outputs_16['OUTPUT'], Score, 0, 10, 0, True, 2, output_layer_alg17)
Can someone please explain the purpose of ['SAVENAME'], ['OUTPUT'] and ['OUTPUT_LAYER']?
I am trying to develop a script but keep getting errors linked to these terms and I am unsure as to how they are used.
