NIO will be removed in next major release.

@Deprecated
public abstract class WritableRepresentation
extends ChannelRepresentation

Representation based on a writable NIO byte channel. This class is a good basis to write your own representations, especially for the dynamic and large ones.

For this you just need to create a subclass and override the abstract Representation.write(WritableByteChannel) method. This method will later be called back by the connectors when the actual representation's content is needed.

Modifier and Type	Method and Description
ReadableByteChannel	getChannel() Deprecated. Returns a channel with the representation's content. If it is supported by a file, a read-only instance of FileChannel is returned.
