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:

Returns:

true if and only if the property has been set
