public abstract class Message extends java.lang.Object
The ANTLR code calls methods on ErrorManager to report errors etc... Rather than simply pass these arguments to the ANTLRErrorListener directly, create an object that encapsulates everything. In this way, the error listener interface does not have to change when I add a new kind of error message. I don't want to break a GUI for example every time I update the error system in ANTLR itself. To get a printable error/warning message, call toString().
