/**
* A selectable channel for message-oriented connected SCTP sockets.
*
* <P> An SCTP channel can only control one SCTP association.
* An {@code SCTPChannel} is created by invoking one of the
* {@link #open open} methods of this class. A newly-created channel is open but
* not yet connected, that is, there is no association setup with a remote peer.
* An attempt to invoke an I/O operation upon an unconnected
* channel will cause a {@link java.nio.channels.NotYetConnectedException} to be
* thrown. An association can be setup by connecting the channel using one of
* its {@link #connect connect} methods. Once connected, the channel remains
* connected until it is closed. Whether or not a channel is connected may be
* determined by invoking {@link #getRemoteAddresses getRemoteAddresses}.
*
* <p> SCTP channels support <i>non-blocking connection:</i> A
* channel may be created and the process of establishing the link to
* the remote socket may be initiated via the {@link #connect connect} method
* for later completion by the {@link #finishConnect finishConnect} method.
* Whether or not a connection operation is in progress may be determined by
* invoking the {@link #isConnectionPending isConnectionPending} method.
*
* <p> Socket options are configured using the
* {@link #setOption(SctpSocketOption,Object) setOption} method. An SCTP
* channel support the following options:
* <blockquote>

* Additional (implementation specific) options may also be supported. The list

*
* <p> SCTP channels are safe for use by multiple concurrent threads.
* They support concurrent reading and writing, though at most one thread may be
* reading and at most one thread may be writing at any given time. The
* {@link #connect connect} and {@link #finishConnect
* finishConnect} methods are mutually synchronized against each other, and
* an attempt to initiate a send or receive operation while an invocation of one
* of these methods is in progress will block until that invocation is complete.
