     if (super.setOption(option, value)) {
         return true;
     }

     if (option.equals(additionalOption)) {

     }

     return false;
 }

    另请参阅:
    RFC 7413 Passive Open
  - setTcpFastopen
```
public EpollServerChannelConfig setTcpFastopen(int pendingFastOpenRequestsThreshold)
```
    Enables tcpFastOpen on the server channel. If the underlying os doesnt support TCP_FASTOPEN setting this has no effect. This has to be set before doing listen on the socket otherwise this takes no effect.
    
    参数:
    pendingFastOpenRequestsThreshold - number of requests to be pending for fastopen at a given point in time for security. @see RFC 7413 Passive Open
    另请参阅:
    RFC 7413 TCP FastOpen
  - setConnectTimeoutMillis
```
public EpollServerChannelConfig setConnectTimeoutMillis(int connectTimeoutMillis)
```
    从接口复制的说明: ChannelConfig
    
    Sets the connect timeout of the channel in milliseconds. If the Channel does not support connect operation, this property is not used at all, and therefore will be ignored.
    
    指定者:
    
    setConnectTimeoutMillis 在接口中 ChannelConfig
    
    覆盖:
    
    setConnectTimeoutMillis 在类中 EpollChannelConfig
    
    参数:
    connectTimeoutMillis - the connect timeout in milliseconds. 0 to disable.
  - setMaxMessagesPerRead
```
public EpollServerChannelConfig setMaxMessagesPerRead(int maxMessagesPerRead)
```
    从接口复制的说明: ChannelConfig
    
    Sets the maximum number of messages to read per read loop. If this value is greater than 1, an event loop might attempt to read multiple times to procure multiple messages.
    
    指定者:
    
    setMaxMessagesPerRead 在接口中 ChannelConfig
    
    覆盖:
    
    setMaxMessagesPerRead 在类中 EpollChannelConfig
  - setWriteSpinCount
```
public EpollServerChannelConfig setWriteSpinCount(int writeSpinCount)
```
    从接口复制的说明: ChannelConfig
    
    Sets the maximum loop count for a write operation until WritableByteChannel.write(ByteBuffer) returns a non-zero value. It is similar to what a spin lock is used for in concurrency programming. It improves memory utilization and write throughput depending on the platform that JVM runs on. The default value is 16.
    
    指定者:
    
    setWriteSpinCount 在接口中 ChannelConfig
    
    覆盖:
    
    setWriteSpinCount 在类中 EpollChannelConfig
  - setAllocator
```
public EpollServerChannelConfig setAllocator(ByteBufAllocator allocator)
```
    从接口复制的说明: ChannelConfig
    
    Set the ByteBufAllocator which is used for the channel to allocate buffers.
    
    指定者:
    
    setAllocator 在接口中 ChannelConfig
    
    覆盖:
    
    setAllocator 在类中 EpollChannelConfig
  - setRecvByteBufAllocator
```
public EpollServerChannelConfig setRecvByteBufAllocator(RecvByteBufAllocator allocator)
```
    从接口复制的说明: ChannelConfig
    
    Set the ByteBufAllocator which is used for the channel to allocate receive buffers.
    
    指定者:
    
    setRecvByteBufAllocator 在接口中 ChannelConfig
    
    覆盖:
    
    setRecvByteBufAllocator 在类中 EpollChannelConfig
  - setAutoRead
```
public EpollServerChannelConfig setAutoRead(boolean autoRead)
```
    从接口复制的说明: ChannelConfig
    
    Sets if ChannelHandlerContext.read() will be invoked automatically so that a user application doesn't need to call it at all. The default value is true.
    
    指定者:
    
    setAutoRead 在接口中 ChannelConfig
    
    覆盖:
    
    setAutoRead 在类中 EpollChannelConfig
  - setWriteBufferHighWaterMark
```
public EpollServerChannelConfig setWriteBufferHighWaterMark(int writeBufferHighWaterMark)
```
    从接口复制的说明: ChannelConfig
    
    Sets the high water mark of the write buffer. If the number of bytes queued in the write buffer exceeds this value, Channel.isWritable() will start to return false.
    
    指定者:
    
    setWriteBufferHighWaterMark 在接口中 ChannelConfig
    
    覆盖:
    
    setWriteBufferHighWaterMark 在类中 EpollChannelConfig
  - setWriteBufferLowWaterMark
```
public EpollServerChannelConfig setWriteBufferLowWaterMark(int writeBufferLowWaterMark)
```
    从接口复制的说明: ChannelConfig
    
    Sets the low water mark of the write buffer. Once the number of bytes queued in the write buffer exceeded the high water mark and then dropped down below this value, Channel.isWritable() will start to return true again.
    
    指定者:
    
    setWriteBufferLowWaterMark 在接口中 ChannelConfig
    
    覆盖:
    
    setWriteBufferLowWaterMark 在类中 EpollChannelConfig
  - setMessageSizeEstimator
```
public EpollServerChannelConfig setMessageSizeEstimator(MessageSizeEstimator estimator)
```
    从接口复制的说明: ChannelConfig
    
    Set the MessageSizeEstimator which is used for the channel to detect the size of a message.
    
    指定者:
    
    setMessageSizeEstimator 在接口中 ChannelConfig
    
    覆盖:
    
    setMessageSizeEstimator 在类中 EpollChannelConfig
  - setEpollMode
```
public EpollServerChannelConfig setEpollMode(EpollMode mode)
```
    从类复制的说明: EpollChannelConfig
    
    Set the EpollMode used. Default is EpollMode.EDGE_TRIGGERED. If you want to use DefaultChannelConfig.isAutoRead() false or DefaultChannelConfig.getMaxMessagesPerRead() and have an accurate behaviour you should use EpollMode.LEVEL_TRIGGERED. Be aware this config setting can only be adjusted before the channel was registered.
