接口 NioSocketChannelConfig

所有超级接口：

ChannelConfig, SocketChannelConfig

public interface NioSocketChannelConfig
extends SocketChannelConfig

一个NIO TCP/IP SocketChannel的SocketChannelConfig.

有效属性

ChannelConfig和SocketChannelConfig还提供其他的属性, NioSocketChannelConfig有以下属性:

名称	关联setter方法
"writeBufferHighWaterMark"	setWriteBufferHighWaterMark(int)
"writeBufferLowWaterMark"	setWriteBufferLowWaterMark(int)
"writeSpinCount"	setWriteSpinCount(int)
"receiveBufferSizePredictor"	setReceiveBufferSizePredictor(ReceiveBufferSizePredictor)
"receiveBufferSizePredictorFactory"	setReceiveBufferSizePredictorFactory(ReceiveBufferSizePredictorFactory)

方法摘要

ReceiveBufferSizePredictor	getReceiveBufferSizePredictor() 返回用来预测套接字接收缓冲的可读字节数的ReceiveBufferSizePredictor.默认预测机是 AdaptiveReceiveBufferSizePredictor(64, 1024, 65536).
ReceiveBufferSizePredictorFactory	getReceiveBufferSizePredictorFactory() 返回当一个新通道被创建和ReceiveBufferSizePredictor没有被设置时创建一个新的 ReceiveBufferSizePredictor的 ReceiveBufferSizePredictorFactory.如果该通道没有设置预测机,带有新预测机的 setReceiveBufferSizePredictor(ReceiveBufferSizePredictor)方法会被调用.
int	getWriteBufferHighWaterMark() 返回写缓冲的高水位标记.如果写缓冲队列里的字节数超过该值,Channel.isWritable()会开始返回 true.
int	getWriteBufferLowWaterMark() 返回写缓冲的低水位标记.一旦写缓冲队列里字节数超过 高水位标记,随后回落到该值,Channel.isWritable()会重新返回true.
int	getWriteSpinCount() 返回写操作的最大回路数直到WritableByteChannel.write(ByteBuffer) 返回一个非零值为止.它类似在并发编程里使用什么样的自旋锁.它利用JVM所运行的平台改善内存利用率和写的吞吐量.默认值为16.
void	setReceiveBufferSizePredictor(ReceiveBufferSizePredictor predictor) 设置用来预测套接字接收缓冲的可读字节数的ReceiveBufferSizePredictor.默认预测机是 AdaptiveReceiveBufferSizePredictor(64, 1024, 65536).
void	setReceiveBufferSizePredictorFactory(ReceiveBufferSizePredictorFactory predictorFactory) 设置当一个新通道被创建和ReceiveBufferSizePredictor没有被设置时创建一个新的 ReceiveBufferSizePredictor的 ReceiveBufferSizePredictorFactory.如果该通道没有设置预测机,带有新预测机的 setReceiveBufferSizePredictor(ReceiveBufferSizePredictor)方法会被调用.
void	setWriteBufferHighWaterMark(int writeBufferHighWaterMark) 设置写缓冲的高水位标记.如果写缓冲队列里的字节数超过该值,Channel.isWritable()会开始返回 true.
void	setWriteBufferLowWaterMark(int writeBufferLowWaterMark) 设置写缓冲的低水位标记.一旦写缓冲队列里字节数超过 高水位标记,随后回落到该值,Channel.isWritable()会重新返回true.
void	setWriteSpinCount(int writeSpinCount) 设置写操作的最大回路数直到WritableByteChannel.write(ByteBuffer) 返回一个非零值为止.它类似在并发编程里使用什么样的自旋锁.它利用JVM所运行的平台改善内存利用率和写的吞吐量.默认值为16.

方法详细信息

getWriteBufferHighWaterMark

int getWriteBufferHighWaterMark()

返回写缓冲的高水位标记.如果写缓冲队列里的字节数超过该值,Channel.isWritable()会开始返回 true.

setWriteBufferHighWaterMark

void setWriteBufferHighWaterMark(int writeBufferHighWaterMark)

设置写缓冲的高水位标记.如果写缓冲队列里的字节数超过该值,Channel.isWritable()会开始返回 true.

getWriteBufferLowWaterMark

int getWriteBufferLowWaterMark()

返回写缓冲的低水位标记.一旦写缓冲队列里字节数超过 高水位标记,随后回落到该值,Channel.isWritable()会重新返回true.

setWriteBufferLowWaterMark

void setWriteBufferLowWaterMark(int writeBufferLowWaterMark)

设置写缓冲的低水位标记.一旦写缓冲队列里字节数超过 高水位标记,随后回落到该值,Channel.isWritable()会重新返回true.

getWriteSpinCount

int getWriteSpinCount()

返回写操作的最大回路数直到WritableByteChannel.write(ByteBuffer) 返回一个非零值为止.它类似在并发编程里使用什么样的自旋锁.它利用JVM所运行的平台改善内存利用率和写的吞吐量.默认值为16.

setWriteSpinCount

void setWriteSpinCount(int writeSpinCount)

设置写操作的最大回路数直到WritableByteChannel.write(ByteBuffer) 返回一个非零值为止.它类似在并发编程里使用什么样的自旋锁.它利用JVM所运行的平台改善内存利用率和写的吞吐量.默认值为16.

抛出：

java.lang.IllegalArgumentException - 如果指定的值是0或小于0,则抛出异常

getReceiveBufferSizePredictor

ReceiveBufferSizePredictor getReceiveBufferSizePredictor()

返回用来预测套接字接收缓冲的可读字节数的ReceiveBufferSizePredictor.默认预测机是 AdaptiveReceiveBufferSizePredictor(64, 1024, 65536).

setReceiveBufferSizePredictor

void setReceiveBufferSizePredictor(ReceiveBufferSizePredictor predictor)

设置用来预测套接字接收缓冲的可读字节数的ReceiveBufferSizePredictor.默认预测机是 AdaptiveReceiveBufferSizePredictor(64, 1024, 65536).

getReceiveBufferSizePredictorFactory

ReceiveBufferSizePredictorFactory getReceiveBufferSizePredictorFactory()
