Example 11 with Visitor

use of org.codehaus.groovy.antlr.treewalker.Visitor in project groovy-core by groovy.

the class GroovyRootDocBuilder method parseJava.

    } catch (OutOfMemoryError e) {
        log.error("Out of memory while processing: " + packagePath + "/" + file);
        throw e;
    }
    AST ast = parser.getAST();
    // modify the Java AST into a Groovy AST (just token types)
    Visitor java2groovyConverter = new Java2GroovyConverter(tokenNames);
    AntlrASTProcessor java2groovyTraverser = new PreOrderTraversal(java2groovyConverter);
    java2groovyTraverser.process(ast);
    // now mutate (groovify) the ast into groovy
    Visitor groovifier = new Groovifier(tokenNames, false);
