AbstractScheduledEventExecutor (Netty API Reference (4.1.22.Final))

java.lang.Object
- java.util.concurrent.AbstractExecutorService
- - io.netty.util.concurrent.AbstractEventExecutor
  - - io.netty.util.concurrent.AbstractScheduledEventExecutor

All Implemented Interfaces:

EventExecutor ， EventExecutorGroup ，java.lang.Iterable < EventExecutor >，java.util.concurrent.Executor，java.util.concurrent.ExecutorService中，java.util.concurrent.ScheduledExecutorService

已知直接子类：

GlobalEventExecutor ， SingleThreadEventExecutor
```
public abstract class AbstractScheduledEventExecutor
extends AbstractEventExecutor
```
希望支持调度的抽象基类EventExecutor 。

    取消所有计划任务。只有当AbstractEventExecutor.inEventLoop()是true时，才必须调用此方法。
  - pollScheduledTask
```
protected final java.lang.Runnable pollScheduledTask()
```
    另请参见：
    
    pollScheduledTask(long)
  - pollScheduledTask
```
protected final java.lang.Runnable pollScheduledTask(long nanoTime)
```
    返回Runnable ，准备nanoTime给定的nanoTime执行。您应该使用nanoTime()来检索正确的nanoTime 。
  - nextScheduledTaskNano
```
protected final long nextScheduledTaskNano()
```
    当下一个计划任务准备好运行时返回纳秒 -1如果没有计划任务，则返回 -1 。
  - hasScheduledTasks
```
protected final boolean hasScheduledTasks()
```
    如果计划任务已准备好处理，则返回 true 。
