ChannelEndPoint

public ChannelEndPoint(ByteChannel channel,
                       ManagedSelector selector,
                       SelectionKey key,
                       org.eclipse.jetty.util.thread.Scheduler scheduler)

方法详细资料

isOptimizedForDirectBuffers

public boolean isOptimizedForDirectBuffers()

从接口复制的说明: EndPoint

Is the endpoint optimized for DirectBuffer usage

指定者:

isOptimizedForDirectBuffers 在接口中 EndPoint

覆盖:

isOptimizedForDirectBuffers 在类中 AbstractEndPoint

返回:

True if direct buffers can be used optimally.

isOpen

public boolean isOpen()

从类复制的说明: IdleTimeout

This abstract method should be called to check if idle timeouts should still be checked.

指定者:

isOpen 在接口中 EndPoint

覆盖:

isOpen 在类中 AbstractEndPoint

返回:

True if the entity monitored should still be checked for idle timeouts

doClose

public void doClose()

覆盖:

doClose 在类中 AbstractEndPoint

onClose

public void onClose()

从接口复制的说明: EndPoint

Callback method invoked when this EndPoint is close.

指定者:

onClose 在接口中 EndPoint

覆盖:

onClose 在类中 AbstractEndPoint

另请参阅:

EndPoint.onOpen()

fill

public int fill(ByteBuffer buffer)
         throws IOException

从接口复制的说明: EndPoint

Fill the passed buffer with data from this endpoint. The bytes are appended to any data already in the buffer by writing from the buffers limit up to it's capacity. The limit is updated to include the filled bytes.

指定者:

fill 在接口中 EndPoint

参数:

buffer - The buffer to fill. The position and limit are modified during the fill. After the operation, the position is unchanged and the limit is increased to reflect the new data filled.

返回:

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

抛出:

IOException - if the endpoint is closed.

flush

public boolean flush(ByteBuffer... buffers)
              throws IOException

从接口复制的说明: EndPoint

Flush data from the passed header/buffer to this endpoint. As many bytes as can be consumed are taken from the header/buffer position up until the buffer limit. The header/buffers position is updated to indicate how many bytes have been consumed.

指定者:

flush 在接口中 EndPoint

参数:

buffers - the buffers to flush

返回:

True IFF all the buffers have been consumed and the endpoint has flushed the data to its destination (ie is not buffering any data).

抛出:

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

getChannel

public ByteChannel getChannel()

getTransport

public Object getTransport()

指定者:

getTransport 在接口中 EndPoint

返回:

The underlying transport object (socket, channel, etc.)

needsFillInterest

protected void needsFillInterest()

指定者:

needsFillInterest 在类中 AbstractEndPoint

onIncompleteFlush

protected void onIncompleteFlush()

指定者:

onIncompleteFlush 在类中 AbstractEndPoint

onSelected

public Runnable onSelected()

从接口复制的说明: ManagedSelector.Selectable

Callback method invoked when a read or write events has been detected by the ManagedSelector for this endpoint.

指定者:

onSelected 在接口中 ManagedSelector.Selectable

返回:

a job that may block or null

updateKey

public void updateKey()

从接口复制的说明: ManagedSelector.Selectable

Callback method invoked when all the keys selected by the ManagedSelector for this endpoint have been processed.

指定者:

updateKey 在接口中 ManagedSelector.Selectable

toEndPointString

public String toEndPointString()

覆盖:

toEndPointString 在类中 AbstractEndPoint
