MessageConsumerAdapter (QD Core API 3.342)

java.lang.Object
- com.devexperts.qd.qtp.MessageConsumerAdapter

All Implemented Interfaces:

MessageConsumer, SymbolCodec.Resolver

Direct Known Subclasses:

MessageAdapter
```
public class MessageConsumerAdapter
extends Object
implements MessageConsumer, SymbolCodec.Resolver
```
Implementation of MessageConsumer that does nothing. Error methods in this implementation write message to the log file with Logging.error(java.lang.String) and all functional methods skip incoming data and call handleUnknownMessage(int).
