Parse .java files

Hello,

I am using JavaParser (Java Source Reflection) to parse .java files, but what I really want is to get the info from the comments, Javadoc and simple // comments.

JavaParser parses only the code and not the comments. So:

Code:

---

JavaMethod[] methods = js.getMethods();
for (int i = 0;  i < methods.length;  i++) {
    System.out.println("  " + methods[i].getName());
    System.out.println("    " + methods[i].getComment());
}

---

gives the names of the methods but null for the javadoc comments.

I am using netbeans. Do you know which library should I use?

If you have access to a .java file, why don't you parse it yourself for the comments? Just look for the method declaration, and search within the brackets for any occurrences of "//".

Thanks 4 your answer ra4king.

..Because I need to take the comments separately from the methods, then from the description of the class, then from the fields and then any other "//" comments.
I want this to work with any source file with unknown to me structure, not only this particularly.

Is there a parser at all? I can't find a parser to work like this.

I am making my own parser.

If I know the method's name in the source code, how can I take the previous lines that contain the method Javadoc?

for the author's name, I have done the following code.

Code:

---

FileInputStream fstream = new FileInputStream(pFile.getAbsolutePath());
            // Get the object of DataInputStream
            DataInputStream in = new DataInputStream(fstream);
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            // Read File Line By Line
            while ((strLine = br.readLine()) != null) {
                // Print the content on the console
                // System.out.println (strLine);
                if (strLine.contains("* @author")){
                    author = strLine.substring("* @author".length()+2);
                    System.out.println("Author: " + author);
                    System.out.println();
                }
}
.........e.t.c

---

I wouldn't suggest doing "substring("* @author*.length()+2)" because you may not know how many stars and spaces there might be. try doing:

Code:

---

strLine.substring(strLine.indexOf("@author")+8);

---

If you want the comments right before a method, I would suggest storing all the lines in an ArrayList first then, after searching and finding the method declaration, parse the previous lines for the comments.

ok!! I did do that with the ArrayList and it worked!

I will try the tip you told me..

Thanks again, good luck at you do!

Before you start implementing everything yourself, read the API documentation for the Doclet class in the JavaDoc documentation. A Doc instance tells you about the comment part of several details of a Java program (methods, classes, fields etc.)

kind regards,

Jos

Where is this Doclet class? I can't seem to find it :/

Here.

Hm, I have actually never ventured into the "com" package. Pretty cool classes over there!
