A
ServerSocketChannel
is a partial abstraction of a selectable,
stream-oriented listening socket. Binding and manipulation of socket options
can only be done through the associated
ServerSocket
object, returned
by calling
socket()
. ServerSocketChannels can not be constructed for
an already existing server-socket, nor can a
SocketImpl
be assigned.
A server-socket channel is open but not bound when created by the
open()
method. Calling
accept
before bound will cause a
NotYetBoundException
. It can be bound by calling the bind method of a
related
ServerSocket
instance.

Accepts a connection to this server-socket channel.
This method returns
null
when this channel is non-blocking and no
connection is available, otherwise it blocks until a new connection is
available or an I/O error occurs. The socket channel returned by this
method will always be in blocking mode.
This method just executes the same security checks as the
accept()
method of the
ServerSocket
class.

null

the channel is non-blocking and no connection is available.
AsynchronousCloseException | if this channel is closed by another thread while this method is in operation. |

ClosedByInterruptException | if another thread interrupts the calling thread while this operation is in progress. The interrupt state of the calling thread is set and the channel is closed. |
ClosedChannelException | if this channel is closed. |
IOException | if another I/O error occurs. |
NotYetBoundException | if the socket has not yet been bound. |
Creates an open and unbound server-socket channel.
This channel is created by calling
openServerSocketChannel
method
of the default
SelectorProvider
instance.
IOException | if an I/O error occurs. |

Return the server-socket assigned this channel, which does not declare
any public methods that are not declared in
ServerSocket
.
Gets the valid operations of this channel. Server-socket channels support
accepting operation, so this method returns
SelectionKey.OP_ACCEPT
.
