TextGUIListener (cdk 2.10 API)

java.lang.Object
- org.openscience.cdk.io.listener.TextGUIListener

All Implemented Interfaces:

EventListener, IChemObjectIOListener, IReaderListener, IWriterListener
```
public class TextGUIListener
extends Object
implements IReaderListener, IWriterListener
```
Allows processing of IOSetting quesions which are passed to the user by using the System.out and System.in by default.
This listener can also be used to list all the questions a ChemObjectWriter has, by using a dummy StringWriter, and a null Reader.
