Interface ParseTreeListener

All Known Implementing Classes:
Parser.TraceListener, Parser.TrimToSizeListener
public interface ParseTreeListener
This interface describes the minimal core of methods triggered by ParseTreeWalker. E.g., ParseTreeWalker walker = new ParseTreeWalker(); walker.walk(myParseTreeListener, myParseTree); invalid input: '<'-- triggers events in your listener If you want to trigger events in multiple listeners during a single tree walk, you can use the ParseTreeDispatcher object available at https://github.com/antlr/antlr4/issues/841
