/**@class java.nio.channels.Channel
 implements java.io.Closeable

 A nexus for I/O operations.

 <p> A channel represents an open connection to an entity such as a hardware
 device, a file, a network socket, or a program component that is capable of
 performing one or more distinct I/O operations, for example reading or
 writing.

 <p> A channel is either open or closed.  A channel is open upon creation,
 and once closed it remains closed.  Once a channel is closed, any attempt to
 invoke an I/O operation upon it will cause a {@link java.nio.channels.ClosedChannelException}
 to be thrown.  Whether or not a channel is open may be tested by invoking
 its {@link #isOpen isOpen} method.

 <p> Channels are, in general, intended to be safe for multithreaded access
 as described in the specifications of the interfaces and classes that extend
 and implement this interface.

 operations upon it will cause a {@link java.nio.channels.ClosedChannelException} to be

 effect.

 <p> This method may be invoked at any time.  If some other thread has
 already invoked it, however, then another invocation will block until
 the first invocation is complete, after which it will return without
 effect. </p>
