| * Wraps {@link XMLErrorHandler} and make it look like a SAX {@link ErrorHandler}. |
| * |
| * <p> |
| * The derived class should override the {@link #getErrorHandler()} method |
| * so that it will return the correct {@link XMLErrorHandler} instance. |
| * This method will be called whenever an error/warning is found. |
| * |
| * <p> |
| * Experience shows that it is better to store the actual |
| * {@link XMLErrorHandler} in one place and looks up that variable, |
| * rather than copying it into every component that needs an error handler |
| * and update all of them whenever it is changed, IMO. |
