All Known Implementing Classes:

DefaultPreprocessorListener
```
public interface 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.
