Example 1 with ReqBlocksHeaders

use of org.aion.zero.impl.sync.msg.ReqBlocksHeaders in project aion by aionnetwork.

the class TaskGetHeaders method run.

@Override

    Set<Integer> ids = new HashSet<>();
    Collection<INode> preFilter = this.p2p.getActiveNodes().values();
    List<INode> filtered = preFilter.stream().filter((n) -> n.getTotalDifficulty() != null && n.getTotalDifficulty().compareTo(this.selfTd) >= 0).collect(Collectors.toList());
