public class NioSctpChannel
extends AbstractNioMessageChannel
implements SctpChannel

SctpChannel implementation which use non-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+.

Constructor Details

NioSctpChannel

public NioSctpChannel()

Create a new instance

NioSctpChannel

public NioSctpChannel(SctpChannel sctpChannel)

Create a new instance using SctpChannel

NioSctpChannel

public NioSctpChannel(Channel parent,
 SctpChannel sctpChannel)

Create a new instance

Parameters:

parent - the Channel which is the parent of this NioSctpChannel or null.

sctpChannel - the underlying SctpChannel

Method Details

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 SctpChannel

Overrides:

localAddress in class AbstractChannel

Returns:

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

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

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.

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
