public class NioSctpServerChannel
extends AbstractNioMessageChannel
implements SctpServerChannel

SctpServerChannel implementation which use non-blocking mode to accept new connections and create the NioSctpChannel 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+.

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

allLocalAddresses

public java.util.Set<java.net.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

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

isActive

public boolean isActive()

Description copied from interface: Channel

Return true if the Channel is active and so connected.

Specified by:

isActive in interface Channel

remoteAddress

public java.net.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 java.net.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.
