> The following areas in DefaultTuple.java can be changed:
> The member methods get(), set(), getType() and isNull() all call checkBounds() which
is redundant call since all these 4 functions throw ExecException. Instead of doing a bounds
check, we can catch the IndexOutOfBounds exception in a try-catch and throw it as an ExecException
> The write() method has the following unused object (d in the code below):
> {code}
> for (int i = 0; i < sz; i++) {
>                 try {
>                     Object d = get(i);
>                 } catch (ExecException ee) {
>                     throw new RuntimeException(ee);
>                 }
>                 DataReaderWriter.writeDatum(out, mFields.get(i));
>             }
> {code}
> {noformat}
> The get(i) call in the try should be replaced by the writeDatum call directly since d
is never used and there is an unncessary call to get()
> {noformat}
