Class CrAwareLexerSimulator

  • public class CrAwareLexerSimulator
extends org.antlr.v4.runtime.atn.LexerATNSimulator
    Extends the LexerATNSimulator class in order to override the 'consume()' method so that we can handle '\r' line endings (pre-OSX macOS line endings) correctly in the ANTLR lexer.
