static void antlr.Parser.panic ( ) [static]

Deprecated:: as of 2.7.2. This method calls System.exit() and writes directly to stderr, which is usually not appropriate when a parser is embedded into a larger application. Since the method is static, it cannot be overridden to avoid these problems. ANTLR no longer uses this method internally or in generated code.

Member Data Documentation

ASTFactory antlr.Parser.astFactory = null [protected]

AST support code; parser delegates to this object. This is set during parser construction by default to either "new ASTFactory()" or a ctor that has a token type to class map for hetero nodes.
