[news.eclipse.tools] Rendering of CompilationUnit

[gregor.karl.frey@xxxxxxx (Gregor Frey)]

Hi,
I'm seaking a way to render the content of a CompilationUnit from the
org.eclipse.jdt.core.dom package. Is there a way to transform it in pretty
source code?
I got the CompilationUnit with the AST-parser, changed it a bit and wanted
to write it back to the original IJavaElement. But I can not find a way to
do that.
Can anyone help?

        SourceType source = ... // coming from somewhere
	ICompilationUnit iUnit = source.getCompilationUnit();
	CompilationUnit unit = AST.parseCompilationUnit(iUnit, false);
        ... // working on unit
        // unit -> source

Thanks,
Gregor
