The reason why the pausing (called a holdCount
in the code) is necessary is to ensure that while you're handling the activation values from the SignalCapture
, you don't miss the next values in the sequence that might be delivered from another thread. In sequence delivery with no lost values is the primary requirement of reactive programming.
I should clarify that it's only the branch of the graph that travels through your own SignalCapture
node that is paused (any other listeners won't be paused). Values travelling through the SignalCapture
branch are simply queued until you connect somewhere for them to go.

Interesting. I think I would have suspected the default behavior to be capturing the activation values, but then allowing the signal behavior to pass through. For instance, since your output
signal was continuous
in your example, I would have expected to only see the value 4
once I subscribed (with the activation value of 2
). But capture seems to almost change it to a replay
type after capturing activation values.
