Selector

public Selector()

Selector

public Selector(List<Task<T>> children)

Selector

public Selector(Task<T> first,
 @Nullable
 Task<T> second)

方法详细资料

onChildRunning

protected void onChildRunning(Task<T> child)

从类复制的说明: SingleRunningChildBranch

子类如果支持内联，则重写该方法

覆盖:

onChildRunning 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;
      inlinedHolder.reset();
      // 尝试计算结果（记得处理取消）
      ...
      // 如果未得出结果
      if (!isExecuting()) {
          template_execute();
      }
  }
 

ps: 推荐子类重复编码避免调用super

覆盖:

onChildCompleted 在类中 SingleRunningChildBranch<T>
