public Interface ParseTreeListener

Known Direct Implementers: org.antlr.v4.runtime.Parser.TraceListener, org.antlr.v4.runtime.Parser.TrimToSizeListener
Imports: org.antlr.v4.runtime.ParserRuleContext, org.antlr.v4.runtime.misc.NotNull

This interface describes the minimal core of methods triggered by 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 tree walk, you can use the ParseTreeDispatcher object available at https://github.com/antlr/antlr4/issues/841
