Constructor Details

AioSession

public AioSession()

Method Details

writeBuffer

public abstract WriteBuffer writeBuffer()

获取WriteBuffer用以数据输出

Returns:

WriteBuffer

readBuffer

public abstract ByteBuffer readBuffer()

获取读缓冲区对象

close

public final void close()

强制关闭当前AIOSession。

若此时还存留待输出的数据，则会导致该部分数据丢失

awaitRead

public abstract void awaitRead()

signalRead

public abstract void signalRead()

继续触发读行为，该方法仅可在异步处理模式下可使用，否则会触发不可预知的异常

close

public abstract void close(boolean immediate)

是否立即关闭会话

Parameters:

immediate - true:立即关闭,false:响应消息发送完后关闭

getSessionID

public String getSessionID()

获取当前Session的唯一标识

Returns:

sessionId

isInvalid

public boolean isInvalid()

当前会话是否已失效

Returns:

是否失效

getAttachment

public final <A> A getAttachment()

获取附件对象

Type Parameters:

A - 附件对象类型

Returns:

附件

setAttachment

public final <A> void setAttachment(A attachment)

存放附件，支持任意类型

Type Parameters:

A - 附件对象类型

Parameters:

attachment - 附件对象

getLocalAddress

public abstract InetSocketAddress getLocalAddress()
                                           throws IOException

获取当前会话的本地连接地址

Returns:

本地地址

Throws:

IOException - IO异常

See Also:

• AsynchronousSocketChannel.getLocalAddress()

getRemoteAddress

public abstract InetSocketAddress getRemoteAddress()
                                            throws IOException

获取当前会话的远程连接地址

Returns:

远程地址

Throws:

IOException - IO异常

See Also:

• AsynchronousSocketChannel.getRemoteAddress()

getInputStream

public InputStream getInputStream()
                           throws IOException

获得数据输入流对象。

faster模式下调用该方法会触发UnsupportedOperationException异常。

MessageProcessor采用异步处理消息的方式时，调用该方法可能会出现异常。

Returns:
