Hi

I'm implementing quick assist based on the selection in the editor, using JDT/AST.

Can you let me know how to find the starting line number of the Method Declaration (excluding the Javadocs).

Below code gives me the Line number, but it starts with the JavaDoc comment line number. But I need to get the line number at the Method declaration level.

      public boolean visit(MethodDeclaration node) {
			CompilationUnit cu = getCompilationUnit();
			int startLineNumber =  getCompilationUnit().getLineNumber(node.getStartPosition()));
     ---
     }

Sample Method:

In below sample code, I need to get the Line Number as #14 (from method signature), but Im getting line number as #10 (from Javadoc).

 #10:   /**
#11:     * Method used for extracting the given parameter form the request.return
#12:     * null if empty
#13:     */
#14:     private String getString(HttpServletRequest request, String param)
#15:    {
#16:

I am not sure you can really do it this way. One way you can do is to get the modifiers (i.e. the child of this node that is expected to be in front) and get its start position.

Use MethodDeclaration.getName() to do that.
