     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

Specified by:

setBacklog in interface ServerSocketChannelConfig

setRcvAllocTransportProvidesGuess

public KQueueServerChannelConfig setRcvAllocTransportProvidesGuess(boolean transportProvidesGuess)

Overrides:

setRcvAllocTransportProvidesGuess in class KQueueChannelConfig

setPerformancePreferences

public KQueueServerChannelConfig setPerformancePreferences(int connectionTime,
                                                           int latency,
