TraceWriter

All Known Implementing Classes:

TraceSystem, TraceWriterAdapter
```
interface TraceWriter
```
The backend of the trace system must implement this interface. Two implementations are supported: the (default) native trace writer implementation that can write to a file and to system out, and an adapter that uses SLF4J (Simple Logging Facade for Java).
