Method Detail

getOptions

public Map<io.netty.channel.ChannelOption<?>,Object> getOptions()

Specified by:

getOptions in interface io.netty.channel.ChannelConfig

Overrides:

getOptions in class EpollChannelConfig

getOption

public <T> T getOption(io.netty.channel.ChannelOption<T> option)

Specified by:

getOption in interface io.netty.channel.ChannelConfig

Overrides:

getOption in class EpollChannelConfig

setOption

public <T> boolean setOption(io.netty.channel.ChannelOption<T> option,
                    T value)

Specified by:

setOption in interface io.netty.channel.ChannelConfig

Overrides:

setOption in class EpollChannelConfig

isReuseAddress

public boolean isReuseAddress()

setReuseAddress

public EpollServerChannelConfig setReuseAddress(boolean reuseAddress)

getReceiveBufferSize

public int getReceiveBufferSize()

setReceiveBufferSize

public EpollServerChannelConfig setReceiveBufferSize(int receiveBufferSize)

getBacklog

public int getBacklog()

setBacklog

public EpollServerChannelConfig setBacklog(int backlog)

getTcpFastopen

public int getTcpFastopen()

Returns threshold value of number of pending for fast open connect.

RFC 7413 Passive Open

setTcpFastopen

public EpollServerChannelConfig setTcpFastopen(int pendingFastOpenRequestsThreshold)

Enables tcpFastOpen on the server channel. If the underlying os doesnt 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 RFC 7413 Passive Open

Overrides:

setMessageSizeEstimator in class EpollChannelConfig

setEpollMode

public EpollServerChannelConfig setEpollMode(EpollMode mode)

Description copied from class: EpollChannelConfig

Set the EpollMode used. Default is EpollMode.EDGE_TRIGGERED. If you want to use DefaultChannelConfig.isAutoRead() false or DefaultChannelConfig.getMaxMessagesPerRead() and have an accurate behaviour you should use EpollMode.LEVEL_TRIGGERED. Be aware this config setting can only be adjusted before the channel was registered.

Overrides:

setEpollMode in class EpollChannelConfig
