how to get index of a node in ListRewrite of Eclipse JDT

Question

I am using Eclipse JDT to modify the AST of a source code. I want to modify a MethodDeclaration node. For that, I visited that using ASTVisitor and made changes. Now I removed the past node and am trying to add the new one at the same place using ListRewrite.insertAt() method. For that I want to get the index of the node before removing it. How can I get the index?

Answer 1

Why not call ListRewrite.replace() instead of first removing then adding?

If that doesn't serve your purpose for some reason, try listRewrite.getOriginalList().indexOf(oldNode) .

Answer 2

You can use an empty statement as a place holder and first replace this node with empty statement. Then make changes to your node. Then replace the empty statement with your node. This looks like a hack but works.
