Currently employs jython v2.2.1.
dts = inData0.getDataTableSpec() input1ColumnIndex= dts.findColumnIndex("H atoms")
iterator = inData0.iterator() while iterator.hasNext(): row = iterator.next() ...
iterator = inData0.iterator() while iterator.hasNext(): row = iterator.next() outContainer.addRowToTable(row)
dts = inData0.getDataTableSpec() shoeSizeColumnIndex= dts.findColumnIndex("Size of Shoe")
dts = inData0.getDataTableSpec() petNamesColumnIndex= dts.findColumnIndex("Name of Pet") iterator = inData0.iterator() row = iterator.next() current_name = str(row.getCell(petNamesColumnIndex))Example use to obtain the floating-point value from a row for a particular column:
dts = inData0.getDataTableSpec() petWeightColumnIndex= dts.findColumnIndex("Weight of Pet") iterator = inData0.iterator() row = iterator.next() current_name = float(str(row.getCell(petWeightColumnIndex)))
dts = inData0.getDataTableSpec() sunshineColumnIndex= dts.findColumnIndex("Days of Sunshine")
