public class OioSctpServerChannel
extends AbstractOioMessageChannel
implements SctpServerChannel

SctpServerChannel implementation which use blocking mode to accept new connections and create the OioSctpChannel for them. Be aware that not all operations systems support SCTP. Please refer to the documentation of your operation system, to understand what you need to do to use it. Also this feature is only supported on Java 7+.

Constructor Detail

OioSctpServerChannel

public OioSctpServerChannel()

Create a new instance with an new SctpServerChannel

OioSctpServerChannel

public OioSctpServerChannel(com.sun.nio.sctp.SctpServerChannel sch)

Create a new instance from the given SctpServerChannel

Parameters:

sch - the SctpServerChannel which is used by this instance

Method Detail

metadata

public ChannelMetadata metadata()

Description copied from interface: Channel

Return the ChannelMetadata of the Channel which describe the nature of the Channel.

Specified by:

metadata in interface Channel

config

public SctpServerChannelConfig config()

Description copied from interface: SctpServerChannel

Returns the SctpServerChannelConfig configuration of the channel.

Specified by:

config in interface Channel

Specified by:

config in interface SctpServerChannel

remoteAddress

public InetSocketAddress remoteAddress()

Description copied from interface: Channel

Returns the remote address where this channel is connected to. The returned SocketAddress is supposed to be down-cast into more concrete type such as InetSocketAddress to retrieve the detailed information.

Specified by:

remoteAddress in interface Channel

Overrides:

remoteAddress in class AbstractChannel

Returns:

the remote address of this channel. null if this channel is not connected. If this channel is not connected but it can receive messages from arbitrary remote addresses (e.g. DatagramChannel, use DefaultAddressedEnvelope.recipient() to determine the origination of the received message as this method will return null.

localAddress

public InetSocketAddress localAddress()

Description copied from interface: Channel

Returns the local address where this channel is bound to. The returned SocketAddress is supposed to be down-cast into more concrete type such as InetSocketAddress to retrieve the detailed information.

Specified by:

localAddress in interface Channel

Specified by:

localAddress in interface SctpServerChannel

Overrides:

localAddress in class AbstractChannel

Returns:

the local address of this channel. null if this channel is not bound.

isOpen

public boolean isOpen()

Description copied from interface: Channel

Returns true if the Channel is open and may get active later

Specified by:

isOpen in interface Channel

localAddress0

protected SocketAddress localAddress0()

Description copied from class: AbstractChannel

Returns the SocketAddress which is bound locally.

Specified by:

localAddress0 in class AbstractChannel

allLocalAddresses

public Set<InetSocketAddress> allLocalAddresses()

Description copied from interface: SctpServerChannel

Return all local addresses of the SCTP server channel. Please note that, it will return more than one address if this channel is using multi-homing

Specified by:

allLocalAddresses in interface SctpServerChannel
