ParseTreeListener

@uml This interface describes the minimal core of methods triggered by {@link ParseTreeWalker}. E.g.,

ParseTreeWalker walker = new ParseTreeWalker(); walker.walk(myParseTreeListener, myParseTree); <-- triggers events in your listener

If you want to trigger events in multiple listeners during a single ree walk, you can use the ParseTreeDispatcher object available at

https://github.com/antlr/antlr4/issues/841

interface ParseTreeListener {

void visitTerminal(TerminalNode node);

void visitErrorNode(ErrorNode node);

void enterEveryRule(ParserRuleContext ctx);

void exitEveryRule(ParserRuleContext ctx);

}
