Allows one event through, and blocks all events after that.
Value— The first event received by this port passes through the output port. Events after that are blocked.
Reset— Resets the node, so that the next event into the
Valueport will be allowed through, and events after that will be blocked.
If the same event hits both the
Value port and the
Reset port, then that data is allowed through, and subsequent events that only hit the
Value port are blocked.
