How to insert line comments in code programmatically in Eclipse

Question

I would like to insert line comments in my code, programmatically. I am visiting a method declaration and i want to insert a line comment (or more) above it, using the AST of the method. Could anyone please give me a code example of how to do that? I have been searching for a long time and no success yet. Thanks in advance.

Answer 1

The only way I can think of, to insert code programmatically, is to open a Filestream and write to the text file at a specific pointer location.

Answer 2

Here's how I would do it:

void insertComment(String comment, OutputStream fos) throws IOException {
 String commentKeyword = "//";
 fos.write(commentKeyword.getBytes());
 fos.write(comment.getBytes());
 fos.write("\r\n".getBytes());
}

I don't think there is a native way to do this...
