Class DefaultPreprocessorListener

java.lang.Object

org.anarres.cpp.DefaultPreprocessorListener

All Implemented Interfaces:

PreprocessorListener

public class DefaultPreprocessorListener
extends java.lang.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.
