Method Details

getOptions

public java.util.Map<ChannelOption<?>, java.lang.Object> getOptions()

Description copied from interface: ChannelConfig

Return all set ChannelOption's.

Specified by:

getOptions in interface ChannelConfig

Overrides:

getOptions in class KQueueChannelConfig

getOption

public <T> T getOption(ChannelOption<T> option)

Description copied from interface: ChannelConfig

Return the value of the given ChannelOption

Specified by:

getOption in interface ChannelConfig

Overrides:

getOption in class KQueueChannelConfig

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:

setOption in interface ChannelConfig

Overrides:

setOption in class KQueueChannelConfig

Returns:

true if and only if the property has been set

setActiveOnOpen

private void setActiveOnOpen(boolean activeOnOpen)

getActiveOnOpen

boolean getActiveOnOpen()

isReusePort

public boolean isReusePort()

Returns true if the SO_REUSEPORT option is set.

setReusePort

public KQueueDatagramChannelConfig setReusePort(boolean reusePort)

Set the SO_REUSEPORT option on the underlying Channel. This will allow to bind multiple KQueueSocketChannels to the same port and so accept connections with multiple threads. Be aware this method needs be called before Channel.bind(java.net.SocketAddress) to have any affect.

setRcvAllocTransportProvidesGuess

public KQueueDatagramChannelConfig setRcvAllocTransportProvidesGuess(boolean transportProvidesGuess)

Description copied from class: KQueueChannelConfig

If this is true then the RecvByteBufAllocator.Handle.guess() will be overridden to always attempt to read as many bytes as kqueue says are available.

Overrides:

setRcvAllocTransportProvidesGuess in class KQueueChannelConfig

setMessageSizeEstimator

public KQueueDatagramChannelConfig setMessageSizeEstimator(MessageSizeEstimator estimator)

Description copied from interface: ChannelConfig

Set the MessageSizeEstimator which is used for the channel to detect the size of a message.

Specified by:

setWriteBufferLowWaterMark

@Deprecated

Overrides:

setWriteBufferLowWaterMark in class KQueueChannelConfig

setWriteBufferHighWaterMark

@Deprecated
public KQueueDatagramChannelConfig setWriteBufferHighWaterMark(int writeBufferHighWaterMark)

setWriteSpinCount

public KQueueDatagramChannelConfig setWriteSpinCount(int writeSpinCount)

Description copied from interface: ChannelConfig

Sets the maximum loop count for a write operation until WritableByteChannel.write(ByteBuffer) returns a non-zero value. It is similar to what a spin lock is used for in concurrency programming.
