抛出：

IOException

方法详细信息

getSelectionKey

public SelectionKey getSelectionKey()

getSelectManager

public SelectorManager getSelectManager()

getConnection

public Connection getConnection()

指定者：

接口 ConnectedEndPoint 中的 getConnection

setConnection

public void setConnection(Connection connection)

指定者：

接口 ConnectedEndPoint 中的 setConnection

getIdleTimestamp

public long getIdleTimestamp()

schedule

public void schedule()

Called by selectSet to schedule handling

asyncDispatch

public void asyncDispatch()

从接口 AsyncEndPoint 复制的描述

Dispatch the endpoint. If it is already dispatched, schedule a redispatch

指定者：

接口 AsyncEndPoint 中的 asyncDispatch

dispatch

public void dispatch()

从接口 AsyncEndPoint 复制的描述

Dispatch the endpoint if it is not already dispatched

指定者：

接口 AsyncEndPoint 中的 dispatch

undispatch

protected boolean undispatch()

Called when a dispatched thread is no longer handling the endpoint. The selection key operations are updated.

返回：

If false is returned, the endpoint has been redispatched and thread must keep handling the endpoint.

cancelTimeout

public void cancelTimeout(Timeout.Task task)

指定者：

接口 AsyncEndPoint 中的 cancelTimeout

scheduleTimeout

public void scheduleTimeout(Timeout.Task task,
                            long timeoutMs)

指定者：

接口 AsyncEndPoint 中的 scheduleTimeout

setCheckForIdle

public void setCheckForIdle(boolean check)

从接口 AsyncEndPoint 复制的描述

Set if the endpoint should be checked for idleness

指定者：

接口 AsyncEndPoint 中的 setCheckForIdle

isCheckForIdle

public boolean isCheckForIdle()

从接口 AsyncEndPoint 复制的描述

Get if the endpoint should be checked for idleness

指定者：

接口 AsyncEndPoint 中的 isCheckForIdle

notIdle

protected void notIdle()

checkIdleTimestamp

public void checkIdleTimestamp(long now)

onIdleExpired

public void onIdleExpired(long idleForMs)

从接口 AsyncEndPoint 复制的描述

Callback when idle.

An endpoint is idle if there has been no IO activity for EndPoint.getMaxIdleTime() and AsyncEndPoint.isCheckForIdle() is true.

指定者：

接口 AsyncEndPoint 中的 onIdleExpired

参数：

idleForMs - TODO

fill

public int fill(Buffer buffer)
         throws IOException

从接口 EndPoint 复制的描述

Fill the buffer from the current putIndex to it's capacity from whatever byte source is backing the buffer. The putIndex is increased if bytes filled. The buffer may chose to do a compact before filling.

指定者：

接口 EndPoint 中的 fill

覆盖：

类 ChannelEndPoint 中的 fill

返回：

an int value indicating the number of bytes filled or -1 if EOF is reached.

抛出：

EofException - If input is shutdown or the endpoint is closed.

IOException

flush

public int flush(Buffer header,
                 Buffer buffer,
                 Buffer trailer)
          throws IOException

从接口 EndPoint 复制的描述

Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done. The passed header/trailer buffers are written before/after the contents of this buffer. This may be done either as gather writes, as a poke into this buffer or as several writes. The implementation is free to select the optimal mechanism.

指定者：

接口 EndPoint 中的 flush

覆盖：

类 ChannelEndPoint 中的 flush

参数：

header - A buffer to write before flushing this buffer. This buffers getIndex is updated.

buffer - The buffer to flush. This buffers getIndex is updated.

trailer - A buffer to write after flushing this buffer. This buffers getIndex is updated.

返回：

the total number of bytes written.

抛出：

IOException

flush

public int flush(Buffer buffer)
          throws IOException

从接口 EndPoint 复制的描述

Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done.

指定者：

接口 EndPoint 中的 flush

覆盖：

类 ChannelEndPoint 中的 flush

参数：

buffer - The buffer to flush. This buffers getIndex is updated.

返回：

the number of bytes written

抛出：

EofException - If the endpoint is closed or output is shutdown.
