Context-free grammars may be augmented with predicates to allow arbitrary semantics and syntactic. By default, ANTLR will generate code in all lexers to test each token against the literals table (the table generated for literal strings), and change the token type if it matches the table. At Twitter, we use it exclusively for query parsing in our search engine. BlockContext. The following method is an example, where you can find the comments show which portion of the grammar was translated to which part of the code. Thus we need an ANTLR independent AST.
