ByteChannel
implements
ReadableByteChannel,
WritableByteChannel
| java.nio.channels.ByteChannel
|
Known indirect subclasses
| DatagramChannel |
A selectable channel for datagram-oriented sockets.
|
| FileChannel |
A channel for reading, writing, mapping, and manipulating a file.
|
| SeekableByteChannel |
A byte channel that maintains a current position and allows the
position to be changed.
|
| SocketChannel |
A selectable channel for stream-oriented connecting sockets.
|
|
A channel that can read and write bytes. This interface simply unifies
ReadableByteChannel and WritableByteChannel; it does not
specify any new operations.
