-
setOption
public <T> boolean setOption(ChannelOption<T> option, T value)
Description copied from interface:ChannelConfig
Sets 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:

if TCP FastOpen is enabled.- See Also:
- RFC 7413 Passive Open
-
setTcpFastOpen
public KQueueServerChannelConfig setTcpFastOpen(boolean enableTcpFastOpen)
Enables TCP FastOpen 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:
