public final class NettyChannelBufferStreamCache

A ByteBuf which is exposed as an InputStream which makes it very easy to use by Camel and other Camel components. Also supported is StreamCache which allows the data to be re-read for example when doing content based routing with XPath.

Important: All the classes from the Camel release that implements StreamCache is NOT intended for end users to create as instances, but they are part of Camels stream-caching functionality.
