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 Value
port 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.
