java.lang.Object
- com.jogamp.gluegen.jcpp.DefaultPreprocessorListener

All Implemented Interfaces:

PreprocessorListener
```
public class DefaultPreprocessorListener
extends Object
implements PreprocessorListener
```
A handler for preprocessor events, primarily errors and warnings. If no PreprocessorListener is installed in a Preprocessor, all error and warning events will throw an exception. Installing a listener allows more intelligent handling of these events.
