Examples of com.facebook.presto.tuple.TupleInfo

com.facebook.presto.tuple.TupleInfo
Tuple layout is:
```
 is_null_0_to_7 is_null_8_to_15 ... fixed_0 fixed_1 ... fixed_N var_off_1 var_off_2 ... var_off_N size var_0 var_1 ... var_N 
```
Note: the null flag for each field is independent of the value of the field. Specifically this api will allow you to read and write the value of fields with the null flag set.
