use of org.codehaus.groovy.antlr.treewalker.SourceCodeTraversal in project groovy by apache.

the class Java2GroovyProcessor method mindmap.

public static String mindmap(String input) throws Exception {
    JavaRecognizer parser = getJavaParser(input);
    String[] tokenNames = parser.getTokenNames();
    parser.compilationUnit();
    AST ast = parser.getAST();
    // modify the Java AST into a Groovy AST
    modifyJavaASTintoGroovyAST(tokenNames, ast);
    String[] groovyTokenNames = getGroovyTokenNames(input);
    // groovify the fat Java-Like Groovy AST
    groovifyFatJavaLikeGroovyAST(ast, groovyTokenNames);
    // now output
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    Visitor visitor = new MindMapPrinter(new PrintStream(baos), groovyTokenNames);
    AntlrASTProcessor traverser = new SourceCodeTraversal(visitor);
    traverser.process(ast);
    return new String(baos.toByteArray());
