not automatically expand the tuple size. That is if you called
TupleFactory.newTuple(int) with a 2, it is okay to call
this function with a 1, but not with a 2 or greater.set in interface Tuplearg0 - Number of the field to set the value for.arg1 - Object to put in the indicated field.ExecException - if the field number is greater than or equal to
