Hello,
I need to change the signature of existing methods (adding/removing
parameters, modifiers, exception, ...)
in a programatic way.
What is the advised way to do it?
I saw the AST, the Scanner and the JDom APIs but none of them seem to
support easily these kinds of modifications.
Thank you
Estelle

You can use AST to find _place_ in source, where you need to make your
changes. Then get IBuffer and replace needed pieces directly in source:
ICompilationUnit wc = m_Method.getCompilationUnit();
IBuffer buffer = wc.getBuffer();
buffer.replace(start, oldLength, value);
