-
getOption
Description copied from interface:ChannelConfig
Return the value of the givenChannelOption
- Specified by:
getOption
in interfaceChannelConfig
- Overrides:
getOption

-
setOption
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:
setOption
in interfaceChannelConfig
- Overrides:
setOption
in classDefaultChannelConfig
- Returns:
true
if and only if the property has been set
