closeable

This interface defines a communication channel for input and output. The Channel interface is a high-level generic interface which is extended by more specific interfaces, such as ReadableByteChannel and WritableByteChannel . Channel defines only two methods : isOpen( ) determines whether a channel is open , and close( ) closes a channel. Channels are open when they are first created. Once closed, a channel remains closed forever, and no further I/O operations may take place through it.

Many channel implementations are interruptible and asynchonously closeable, and implement the InterruptibleChannel interface to advertise this fact. See InterruptibleChannel for details.
