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<T>

onChildCompleted

protected void onChildCompleted(Task<T> 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（记得处理取消）
      ...
      // 如果未得出结果
      if (!isExecuting()) {
          template_execute();
      }
  }

 

覆盖:

onChildCompleted 在类中 SingleRunningChildBranch<T>
