9 * Works a lot like /dev/null on *nix style systems. This class allows
10 * infinite reading and writing. All operatorns "succeed" even if they
11 * don't seem to do anything. This is great for testing writing code or
12 * doing dry runs. When reading, it will produce NULL bytes, so any
13 * application that would like the ability to produce null streams as a
14 * snap-in replacement for any other Bu::Stream, this is the right option.
15 *
16 * As an added feature, the NullStream will track how many bytes it was
17 * asked to read and write, allowing you to use it to determine how many
18 * bytes a write opretion would use without actually writing anything.
