主动选择节点 每次运行时都会重新测试节点的运行条件，选择一个新的可运行节点。 如果新选择的运行节点与之前的运行节点不同，则取消之前的任务。

execute

protected void execute()

从类复制的说明: Task

Task的心跳方法，在Task进入完成状态之前会反复执行。 1.可以根据Task.isExecuteTriggeredByEnter()判断是否是与Task.enter(int)连续执行的。 2.运行中可通过Task.setSuccess()、Task.setFailed(int) ()}、Task.setCancelled()将自己更新为完成状态。 3.不建议直接调用该方法，而是通过模板方法运行。

覆盖:

execute 在类中 SingleRunningChildBranch<E>

onChildCompleted

protected void onChildCompleted(Task<E> child)

从类复制的说明: SingleRunningChildBranch

子类的实现模板：

  protected void onChildCompleted(Task child) {
      runningChild = null;
      // 尝试计算结果
      ...
      // 如果未得出结果
      if (!isExecuting()) {
          template_execute();
      }
  }

 

覆盖:

onChildCompleted 在类中 SingleRunningChildBranch<E>
