I want to clone method a() as method a_copied().
The following code generate two "a_copied()".
Document document = new Document(unit.getBuffer().getContents());
ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setSource(unit.getBuffer().getCharacters());
CompilationUnit cu = (CompilationUnit) parser.createAST(null);
final AST ast = cu.getAST();
final ASTRewrite rewriter = ASTRewrite.create(ast);
ASTVisitor visitor;
visitor = new ASTVisitor() {
public boolean visit(MethodDeclaration node) {
if (!node.isConstructor()) {
MethodDeclaration copied =
(MethodDeclaration)rewriter.createCopyTarget(node);
rewriter.getListRewrite(node.getParent(),
TypeDeclaration.BODY_DECLARATIONS_PROPERTY).insertFirst(copi ed, null);
rewriter.replace(node.getName(),
ast.newSimpleName(node.getName().getIdentifier()+ "_copied"), null );
}
return false;
}
};
cu.accept(visitor);
TextEdit edits = rewriter.rewriteAST(document, null);
edits.apply(document);
unit.getBuffer().setContents(document.get());

I made it this way:
MethodDeclaration copied =
(MethodDeclaration)ASTNode.copySubtree(node.getAST(), node);
copied.setName(node.getAST().newSimpleName(node.getName().ge tIdentifier()+ "_copied"));
rewriter.getListRewrite(node.getParent(),
TypeDeclaration.BODY_DECLARATIONS_PROPERTY).insertAfter(copi ed, node, null);
