Example 1 with Twister2Bolt

use of org.apache.storm.topology.twister2.Twister2Bolt in project twister2 by DSC-SPIDAL.

the class TopologyBuilder method createT2Bolt.

private BoltDeclarer createT2Bolt(String id, Object bolt, Number parallelismHint) {
    Twister2Bolt twister2Bolt = new Twister2Bolt(id, bolt, source -> {
        // the source is not a sink anymore,
        // it is a source for another node(compute node)
        boolean sourceWasInSinkNodes = this.sinkNodes.remove(source);
        if (sourceWasInSinkNodes) {
            this.computeNodes.add(source);
        }
    });
    twister2Bolt.setParallelism(parallelismHint.intValue());
    this.nodes.put(id, twister2Bolt);
    // add all to the sink nodes initially
    this.sinkNodes.add(id);
    return twister2Bolt.getBoltDeclarer();
