ByteChannel

AI-generated Key Takeaways

• ByteChannel is an interface that combines reading and writing bytes, unifying ReadableByteChannel and WritableByteChannel functionalities.

• It inherits core methods like read() and write() for byte manipulation, close() and isOpen() for channel management.

• Notable subclasses include DatagramChannel, FileChannel, SeekableByteChannel, and SocketChannel, each offering specific I/O capabilities.

• This interface primarily focuses on providing a unified contract for byte-oriented channel operations without introducing new methods.

public interface ByteChannel implements ReadableByteChannel WritableByteChannel

Known Indirect Subclasses DatagramChannel, FileChannel, SeekableByteChannel, SocketChannel 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.

Inherited Method Summary

From interface java.nio.channels.ReadableByteChannel

abstract int

read(ByteBuffer dst) Reads a sequence of bytes from this channel into the given buffer.

From interface java.nio.channels.WritableByteChannel

abstract int

write(ByteBuffer src) Writes a sequence of bytes to this channel from the given buffer.

From interface java.nio.channels.Channel

abstract void	close() Closes this channel.
abstract boolean	isOpen() Tells whether or not this channel is open.

From interface java.io.Closeable

abstract void

close() Closes this stream and releases any system resources associated with it.

From interface java.lang.AutoCloseable

abstract void

close() Closes this resource, relinquishing any underlying resources.
