# StreamPool
|
|
# ----------
|
|
#
|
|
# This class represents a channel that is associated with a
|
|
# streaming pool that has no definite end-point. While this
|
|
# may seem a paradox given the stream class of channels, it's
|
|
# in fact dinstinct because streams automatically forward
|
|
# traffic between the two ends of the channel whereas
|
|
# stream pools are always requested data in a single direction.
