If you want to discard the old value without looking at it, you could do
that without constructing a buffer.
If you want to find out whether the value was nameOne before changing it
to nameTwo, you may need a buffer. As Andy pointed out, you may get the
data as two separate events; if the first contains "nam", you don't know
whether that will be followed by "eOne"... or "eO" and "ne", for that
matter.
You *might* be able to do something based on recording how many characters
matched the programmed constant before a mismatch was found, and re-issue
them from the constant rather than from the input. This would avoid
buffering. It would also yield fairly ugly code, especially if there are
several values you're looking for and particularly if some of them start
with the same substring. If you've run serious performance tests and know
that buffering is a major bottleneck (unlikely!), you could try this
approach and see if it helps (also unlikely!).
