如何以编程方式使用IntellijIDEA代码格式化程序？

我使用Eclipse jdt来格式化我生成的java文件,如下所示:

public String format(String code)
        throws MalformedTreeException, BadLocationException {
    Map optiOns= new java.util.HashMap();
    options.put(JavaCore.COMPILER_SOURCE, "1.5");
    options.put(JavaCore.COMPILER_COMPLIANCE, "1.5");
    options.put(JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM, "1.5");

    DefaultCodeFormatterOptions cfOptiOns=
            DefaultCodeFormatterOptions.getDefaultSettings();
    cfOptions.insert_new_line_after_annotation = false;
    cfOptions.comment_insert_new_line_for_parameter = true;

    cfOptions.blank_lines_before_method = 1;
    cfOptions.number_of_empty_lines_to_preserve= 1;

    cfOptions.tab_char = DefaultCodeFormatterOptions.SPACE;

    CodeFormatter cf = new DefaultCodeFormatter(cfOptions, options);

    TextEdit te = cf.format(CodeFormatter.K_UNKNOWN, code, 0,
            code.length(), 0, null);
    IDocument dc = new Document(code);

    te.apply(dc);
    return dc.get();
}

但问题是我如何以编程方式使用Intellij Idea代码格式化程序API？Jetbrains是否推出了任何API？
