Direct Known Subclasses:

TMultiplexedProtocol
```
public abstract class TProtocolDecorator
extends TProtocol
```
TProtocolDecorator forwards all requests to an enclosed TProtocol instance, providing a way to author concise concrete decorator subclasses. While it has no abstract methods, it is marked abstract as a reminder that by itself, it does not modify the behaviour of the enclosed TProtocol.
