template<class T >

constexpr size_t caf::flow::op::merge_sub< T >::default_max_pending_per_input = 8

staticconstexpr

Limits how many items the merge operator pulls in per input.

This is deliberately small to make sure that we get reasonably small "batches" of items per input to make sure all inputs get their turn.

The documentation for this class was generated from the following file:
