Method Details

newChannel

protected AFSYSTEMDatagramChannel newChannel()

Description copied from class: AFDatagramSocket

Creates a new DatagramChannel that is associated with this socket.

Specified by:

newChannel in class AFDatagramSocket<AFSYSTEMSocketAddress>

Returns:

The channel.

newInstance

public static AFSYSTEMDatagramSocket newInstance()
                                          throws IOException

Returns a new AFSYSTEMDatagramSocket instance, using the default AFSocketType.SOCK_DGRAM socket type.

Returns:

The new instance.

Throws:

IOException - on error.

newInstance

public static AFSYSTEMDatagramSocket newInstance(AFSocketType socketType)
                                          throws IOException

Returns a new AFSYSTEMDatagramSocket instance for the given socket type.

Parameters:

socketType - The socket type.

Returns:

The new instance.

Throws:

IOException - on error.

getChannel

public AFSYSTEMDatagramChannel getChannel()

Overrides:

getChannel in class AFDatagramSocket<AFSYSTEMSocketAddress>

getImplExtensions

protected AFSYSTEMSocketImplExtensions getImplExtensions()

Description copied from class: AFDatagramSocket

Returns the internal helper instance for address-specific extensions.

Overrides:

getImplExtensions in class AFDatagramSocket<AFSYSTEMSocketAddress>

Returns:

The helper instance.

getNodeIdentity

public int getNodeIdentity(String name)
                    throws IOException

Retrieves the kernel control ID given a kernel control name. An IOException is thrown if the ID is invalid or could not be accessed due to access restrictions.

Parameters:

name - The control name

Returns:

The control Id.

Throws:

IOException - on error.

getNodeIdentity

public int getNodeIdentity(WellKnownKernelControlNames name)
                    throws IOException

Retrieves the kernel control ID given a kernel control name. An IOException is thrown if the ID is invalid or could not be accessed due to access restrictions.

Parameters:

name - The control name

Returns:

The control Id.

Throws:

IOException - on error.

newDatagramSocketInstance

protected AFDatagramSocket<AFSYSTEMSocketAddress> newDatagramSocketInstance()
                                                                     throws IOException

Description copied from class: AFDatagramSocket

Returns a new AFDatagramSocket instance to be used for AFDatagramSocket.accept(), i.e., no FileDescriptor is associated.

Specified by:

newDatagramSocketInstance in class AFDatagramSocket<AFSYSTEMSocketAddress>

Returns:

The new instance.

Throws:

IOException - on error.

getOption

public <T> T getOption(SocketOption<T> name)
                throws IOException

Overrides:

getOption in class DatagramSocket

Throws:

IOException

setOption

public <T> DatagramSocket setOption(SocketOption<T> name,
 T value)
                             throws IOException

Overrides:

setOption in class DatagramSocket

Throws:

IOException
