private static java.util.VectordetermineOperand(java.util.Vector operands, java.lang.String defaultOperand)
This api will check if the user enters an operand, if not, then replace it with the defaultoperand specified in the CLIDescriptor.xml

        return operands.size()<1 && defaultOperand!=null ?
               new Vector<String>(java.util.Arrays.asList(
               new String[]{defaultOperand})):operands;
