Example 11 with FCPublisher

use of org.nustaq.fastcast.api.FCPublisher in project fast-cast by RuedigerMoeller.

the class ProgrammaticConfiguredPublisher method main.

public static void main(String[] arg) {
    // 5 chars MAX !!
    FastCast.getFastCast().setNodeId("PUB");
    configureFastCast();
    FCPublisher pub = FastCast.getFastCast().onTransport("default").publish(// unique-per-transport topic id
    new PublisherConf(1).numPacketHistory(// how long packets are kept for retransmission requests
    40_000).pps(// packets per second rate limit. So max traffic for topic = 5000*2500 = 12.5 MB/second
    5000));
    // could directly send raw on publisher
    // while( ! pub.offer(..) ) { /* spin */ }
    // or use a helper for fast-serialized messages
    ObjectPublisher opub = new ObjectPublisher(pub);
    RateMeasure measure = new RateMeasure("msg/s");
    while (true) {
        measure.count();
        opub.sendObject(// all listeners should receive (by specifying a nodeId, a specific subscriber can be targeted)
        null, // serializable object
        "Hello " + System.currentTimeMillis(), // allow for 'batching' several messages into one (will create slight latency)
        false);
    }
