java.nio.channels.Channel | Closeable |
A channel is a conduit to IO services covering such items as files, sockets, hardware devices, IO ports, or some software component.
Channels are open upon creation, and can be explicitly closed. Once a channel
is closed it cannot be re-opened, and attempts to perform IO operations on
the closed channel result in a ClosedChannelException
.
Particular implementations or sub-interfaces of Channel dictate whether they are thread-safe or not.
void | close() | |||||
Closes an open channel. | ||||||
boolean | isOpen() | |||||
Returns whether this channel is open or not. |
If an attempt is made to perform an operation on a closed channel then a
ClosedChannelException
will be thrown on that attempt.
If multiple threads attempts to simultaneously close a channel, then only one thread will run the closure code, and others will be blocked until the first returns.
IOException | if a problem occurs closing the channel. |
