```
@Deprecated
@Sharable
public final class BufferConversionHandler
extends Object
implements io.netty5.channel.ChannelHandler
```
Deprecated.
This handler will be moved out of Netty core and into a contrib repository, before Netty 5.0.0.Final is released.

ChannelHandler that converts ByteBuf messages into Buffer messages, and vice versa, depending on configuration.
This class is useful as an intermediate handler that allows ByteBuf-based handlers and Buffer-based handlers to work together in the same pipeline.
It is, however, recommended that all handlers eventually be converted to use the Buffer API, as that is more future-proof.
Instances of this handler are ChannelHandler.Sharable and can be added to multiple pipelines. This is safe because the instances are immutable and thread-safe.
