It's worth mentioning that I do
not
need to override all the polymorphic forms of
print()
and
println()
. Because these all ultimately use one of the forms of
write()
, if you over-
ride the
print
and
println
methods to do the
tee
-ing as well, you can get several additional
copies of the data written out.
