I want to reach a goal like this.

Code:
      SelectValuesMeta BMeta = new SelectValuesMeta();                BMeta.setDefault();

               

                ******
        			meta[0] = new SelectMetadataChange("weight", "weight_rename", ValueMetaInterface.TYPE_NUMBER, -2, -2, -1, "00.0", null, null, null);
                ******


                StepMeta B = new StepMeta("B", BMeta);
                B.setLocation(500, 200);
                B.setDraw(true);
                transMeta.addStep(B);
How should I complete this code.[PDI 3.2]
