Extracting groovy comments and source code

[Saravanan Palanichamy]

Hello all,

I am trying to do two things

1) Extract comments from inside a function code (not the function's groovy doc, 
but comments embedded inside the function code itself)
2) Extract the source code of the function itself

For example

/* Comments about myFunction *./
void myFunction() {
    // My first line in the function
    myFirstLine()

    // My second line
    secondLine()
}

I want to extract the two // comments inside the function. I also want to be 
able to get the entire source code of the function (so essentially the entire 
code snippet above) as part of my AST transformations. Is that possible? Thank 
you for your time

regards
Saravanan
