List of genRecognizer() Examples

Examples of genRecognizer()

org.antlr.codegen.CodeGenerator.genRecognizer()
Given the grammar to which we are attached, walk the AST associated with that grammar to create NFAs. Then create the DFAs for all decision points in the grammar by converting the NFAs to DFAs. Finally, walk the AST again to generate code. Either 1 or 2 files are written: recognizer: the main parser/lexer/treewalker item header file: language like C/C++ need extern definitions The target, such as JavaTarget, dictates which files get written.
