Method Details
-
getOptions
Description copied from interface:ChannelConfigReturn all setChannelOption's.- Specified by:
getOptionsin interfaceChannelConfig- Overrides:
getOptionsin classDefaultChannelConfig
-
getOption
Description copied from interface:ChannelConfigReturn the value of the givenChannelOption- Specified by:
getOptionin interfaceChannelConfig- Overrides:
getOptionin classIoUringChannelConfig
-
setOption
Description copied from interface:ChannelConfigSets a configuration property with the specified name and value. To override this method properly, you must call the super class:public boolean setOption(ChannelOption<T> option, T value) { if (super.setOption(option, value)) { return true; } if (option.equals(additionalOption)) { .... return true; } return false; }- Specified by:
setOptionin interfaceChannelConfig- Overrides:
setOptionin classIoUringChannelConfig- Returns:
trueif and only if the property has been set
-
setPerformancePreferences
public IoUringServerSocketChannelConfig setPerformancePreferences(int connectionTime, int latency, int bandwidth) Description copied from interface:ServerSocketChannelConfigSets the performance preferences as specified inServerSocket.setPerformancePreferences(int, int, int).- Specified by:
setPerformancePreferencesin interfaceServerSocketChannelConfig
-
isReuseAddress
public boolean isReuseAddress()Description copied from interface:ServerSocketChannelConfigGets theStandardSocketOptions.SO_REUSEADDRoption.- Specified by:
isReuseAddressin interfaceServerSocketChannelConfig
-
setReuseAddress
Description copied from interface:ServerSocketChannelConfigSets theStandardSocketOptions.SO_REUSEADDRoption.- Specified by:
setReuseAddressin interfaceServerSocketChannelConfig
-
getReceiveBufferSize
public int getReceiveBufferSize()Description copied from interface:ServerSocketChannelConfigGets theStandardSocketOptions.SO_RCVBUFoption.- Specified by:
getReceiveBufferSizein interfaceServerSocketChannelConfig
-
setReceiveBufferSize
Description copied from interface:ServerSocketChannelConfigGets theStandardSocketOptions.SO_SNDBUFoption.- Specified by:
setReceiveBufferSizein interfaceServerSocketChannelConfig
-
getBacklog
public int getBacklog()Description copied from interface:ServerSocketChannelConfigGets the backlog value to specify when the channel binds to a local address.- Specified by:
getBacklogin interfaceServerSocketChannelConfig
-
setBacklog
Description copied from interface:ServerSocketChannelConfigSets the backlog value to specify when the channel binds to a local address.- Specified by:
setBacklogin interfaceServerSocketChannelConfig
-
setConnectTimeoutMillis
Description copied from interface:ChannelConfigSets the connect timeout of the channel in milliseconds. If theChanneldoes not support connect operation, this property is not used at all, and therefore will be ignored.- Specified by:
setConnectTimeoutMillisin interfaceChannelConfig- Specified by:
setConnectTimeoutMillisin interfaceServerSocketChannelConfig- Overrides:
setConnectTimeoutMillisin classIoUringChannelConfig- Parameters:
connectTimeoutMillis- the connect timeout in milliseconds.0to disable.
-
setMaxMessagesPerRead
Deprecated.Description copied from class:DefaultChannelConfig- Specified by:
setMaxMessagesPerReadin interfaceChannelConfig- Specified by:
setMaxMessagesPerReadin interfaceServerSocketChannelConfig- Overrides:
setMaxMessagesPerReadin classIoUringChannelConfig
-
setWriteSpinCount
Description copied from interface:ChannelConfigSets the maximum loop count for a write operation untilWritableByteChannel.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 is16.- Specified by:
setWriteSpinCountin interfaceChannelConfig- Specified by:
setWriteSpinCountin interfaceServerSocketChannelConfig- Overrides:
setWriteSpinCountin classIoUringChannelConfig
-
setAllocator
Description copied from interface:ChannelConfigSet theByteBufAllocatorwhich is used for the channel to allocate buffers.- Specified by:
setAllocatorin interfaceChannelConfig- Specified by:
setAllocatorin interfaceServerSocketChannelConfig- Overrides:
setAllocatorin classIoUringChannelConfig
-
setRecvByteBufAllocator
Description copied from interface:ChannelConfigSet theRecvByteBufAllocatorwhich is used for the channel to allocate receive buffers.- Specified by:
setRecvByteBufAllocatorin interfaceChannelConfig- Specified by:
setRecvByteBufAllocatorin interfaceServerSocketChannelConfig- Overrides:
setRecvByteBufAllocatorin classIoUringChannelConfig
-
setAutoRead
Description copied from interface:ChannelConfigSets ifChannelHandlerContext.read()will be invoked automatically so that a user application doesn't need to call it at all. The default value istrue.- Specified by:
setAutoReadin interfaceChannelConfig- Specified by:
setAutoReadin interfaceServerSocketChannelConfig- Overrides:
setAutoReadin classIoUringChannelConfig
-
setWriteBufferHighWaterMark
@Deprecated public IoUringServerSocketChannelConfig setWriteBufferHighWaterMark(int writeBufferHighWaterMark) Deprecated.Description copied from interface:ChannelConfigSets 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 returnfalse.- Specified by:
setWriteBufferHighWaterMarkin interfaceChannelConfig- Specified by:
setWriteBufferHighWaterMarkin interfaceServerSocketChannelConfig- Overrides:
setWriteBufferHighWaterMarkin classIoUringChannelConfig
-
setWriteBufferLowWaterMark
@Deprecated public IoUringServerSocketChannelConfig setWriteBufferLowWaterMark(int writeBufferLowWaterMark) Deprecated.Description copied from interface:ChannelConfigSets 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 returntrueagain.- Specified by:
setWriteBufferLowWaterMarkin interfaceChannelConfig- Specified by:
setWriteBufferLowWaterMarkin interfaceServerSocketChannelConfig- Overrides:
setWriteBufferLowWaterMarkin classIoUringChannelConfig
-
setWriteBufferWaterMark
public IoUringServerSocketChannelConfig setWriteBufferWaterMark(WriteBufferWaterMark writeBufferWaterMark) Description copied from interface:ChannelConfigSet theWriteBufferWaterMarkwhich is used for setting the high and low water mark of the write buffer.- Specified by:
setWriteBufferWaterMarkin interfaceChannelConfig- Specified by:
setWriteBufferWaterMarkin interfaceServerSocketChannelConfig- Overrides:
setWriteBufferWaterMarkin classIoUringChannelConfig
-
setMessageSizeEstimator
Description copied from interface:ChannelConfigSet theMessageSizeEstimatorwhich is used for the channel to detect the size of a message.- Specified by:
setMessageSizeEstimatorin interfaceChannelConfig- Specified by:
setMessageSizeEstimatorin interfaceServerSocketChannelConfig- Overrides:
setMessageSizeEstimatorin classIoUringChannelConfig
-
isReusePort
public boolean isReusePort()Returnstrueif the SO_REUSEPORT option is set. -
setReusePort
Set the SO_REUSEPORT option on the underlying Channel. This will allow to bind multipleServerSocketChannels to the same port and so accept connections with multiple threads. Be aware this method needs be called beforeChannel.bind(java.net.SocketAddress)to have any affect. -
isFreeBind
public boolean isFreeBind() -
setFreeBind
-
isIpTransparent
public boolean isIpTransparent() -
setIpTransparent
-
setTcpDeferAccept
Set theTCP_DEFER_ACCEPToption on the socket. Seeman 7 tcpfor more details. -
getTcpDeferAccept
public int getTcpDeferAccept()Returns a positive value if TCP_DEFER_ACCEPT is enabled. -
getTcpFastopen
public int getTcpFastopen()Returns threshold value of number of pending for fast open connect.- See Also:
-
setTcpFastopen
Enables tcpFastOpen on the server channel. If the underlying os doesn't support TCP_FASTOPEN setting this has no effect. This has to be set before doing listen on the socket otherwise this takes no effect.- Parameters:
pendingFastOpenRequestsThreshold- number of requests to be pending for fastopen at a given point in time for security.- See Also:
