Detailed Description

Join multiple packet streams with active inputs.

The PriorityJoin will combine any number of packet streams. You may connect any number of PassiveInput<>'s to the PassiveJoin instance. The combined stream is then provided on the PassiveOutput<> output.

When a packet request is received on Priorityjoin's output, The request will be serviced from the first unthrottled input. The order, in which connectors are connected to the PriorityJoin's input is important: The earlier connected peer has the higher priority and will be serviced first.

Since PriorityJoin allows any number of incoming packet streams, the input connectors are dynamically managed. A special senf::ppi::connect() overload is used to dynamically create the needed input connectors. This hides this extra functionality from the user.

senf::ppi::module::PriorityJoin join;

ppi::connect(module1,join);             // Connect first module to join's input
ppi::connect(module2.some_output,join); // Connect another module to join's input
ppi::connect(join,module3);             // Forward combined stream to module3
Here, module1 has higher priority than module2 which will only be queried if module1 is throttled.
