public class OioSctpChannel
extends AbstractOioMessageChannel
implements SctpChannel

SctpChannel implementation which use blocking mode and allows to read / write SctpMessages to the underlying SctpChannel. 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

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:

Specified by:

localAddress in interface SctpChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

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

Specified by:

remoteAddress in interface SctpChannel

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.

parent

public SctpServerChannel parent()

Description copied from interface: Channel

Returns the parent of this channel.

Specified by:

parent in interface Channel

Specified by:

parent in interface SctpChannel

Overrides:

parent in class AbstractChannel

Returns:

the parent channel. null if this channel does not have a parent channel.
