Examples with JavaRecognizer org.codehaus.groovy.antlr.java.JavaRecognizer used on opensource projects

Example 1 with JavaRecognizer

use of org.codehaus.groovy.antlr.java.JavaRecognizer in project groovy by apache.

the class GroovyRootDocBuilder method getJavaParser.

private static JavaRecognizer getJavaParser(String input, SourceBuffer sourceBuffer) {
    UnicodeEscapingReader unicodeReader = new UnicodeEscapingReader(new StringReader(input), sourceBuffer);
    JavaLexer lexer = new JavaLexer(unicodeReader);
    unicodeReader.setLexer(lexer);
    JavaRecognizer parser = JavaRecognizer.make(lexer);
    parser.setSourceBuffer(sourceBuffer);
    return parser;
}

Example 2 with JavaRecognizer

use of org.codehaus.groovy.antlr.java.JavaRecognizer in project groovy by apache.

the class GroovyRootDocBuilder method parseJava.

private Map<String, GroovyClassDoc> parseJava(String packagePath, String file, String src) throws RecognitionException, TokenStreamException {
    SourceBuffer sourceBuffer = new SourceBuffer();
    JavaRecognizer parser = getJavaParser(src, sourceBuffer);
    String[] tokenNames = parser.getTokenNames();
    try {
        parser.compilationUnit();
    } 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);
    AntlrASTProcessor groovifierTraverser = new PreOrderTraversal(groovifier);
    groovifierTraverser.process(ast);
    // now do the business     
    Visitor visitor = new SimpleGroovyClassDocAssembler(packagePath, file, sourceBuffer, links, properties, false);
    AntlrASTProcessor traverser = new SourceCodeTraversal(visitor);
    traverser.process(ast);
    return ((SimpleGroovyClassDocAssembler) visitor).getGroovyClassDocs();
}

Example 3 with JavaRecognizer

use of org.codehaus.groovy.antlr.java.JavaRecognizer in project groovy-core by groovy.

the class GroovyRootDocBuilder method getJavaParser.

private JavaRecognizer getJavaParser(String input, SourceBuffer sourceBuffer) {
    UnicodeEscapingReader unicodeReader = new UnicodeEscapingReader(new StringReader(input), sourceBuffer);
    JavaLexer lexer = new JavaLexer(unicodeReader);
    unicodeReader.setLexer(lexer);
    JavaRecognizer parser = JavaRecognizer.make(lexer);
    parser.setSourceBuffer(sourceBuffer);
    return parser;
}
