◆ EvalChildrenCounts()

void RLoopManager::EvalChildrenCounts ( )

private

Trigger counting of number of children nodes for each node of the functional graph.

This is done once before starting the event loop. Each action sends an increase children count signal upstream, which is propagated until RLoopManager. Each time a node receives the signal, in increments its children counter. Each node only propagates the signal once, even if it receives it multiple times. Named filters also send an increase children count signal, just like actions, as they always execute during the event loop so the graph branch they belong to must count as active even if it does not end in an action.
