ANTLR Runtime Source Code
ANTLR is a powerful parser generator for multiple programming languages including Java.
ANTLR contains 2 major modules:
ANTLR Runtime Source Code files are provided in the distribution packge (antlr4-4.10.1.zip). You can download them at ANTLR Website.
You can also browse the source code below:
