the number of fields in the tuple.public List<Object> getAll()

with an
argument greater than the fieldNum being passed here. This call will
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.fieldNum
- Number of the field to set the value for.val
- Object to put in the indicated field.ExecException
- if the field number is greater than or equal to
the number of fields in the tuple.public void append(Object val)
Tuple
TupleFactory.newTuple(int)
and then fill in the values with
Tuple.set(int, Object)
, rather
than construct it with TupleFactory.newTuple()
and append values.val
- Object to append to the tuple.public long getMemorySize()
