public class ParserEventSupport

extends java.lang.Object

A class to assist in firing parser events NOTE: I intentionally _did_not_ synchronize the event firing and add/remove listener methods. This is because the add/remove should _only_ be called by the parser at its start/end, and the _same_thread_ should be performing the parsing. This should help performance a tad...
