Hi, can anyone give me an example where the eclipse JDT creates a CAPTURE binding?

I've read several capture conversion tutorials, but when I copy-paste the code, I can never find a capture conversion binding in the Abstract Syntax Tree (using the plugin AST-View for eclipse).

Have you tried snippets from
http://www.ibm.com/developerworks/java/library/j-jtp04298.ht ml (same
link which was mentioned in an earlier ans)?

Look for 'KIND' attribute in a type binding node.

I read that tutorial. I think no capture bindings are created...

public void rebox(Box<?> box) {
box.put(box.get());
}
see binding for box.get()

You're right.

I was only trying with code snippets that didn't generate errors, that's why.

Does this mean, that Capture bindings are only created in erroneous code?

Not a smart question

try with
public void rebox(Box<?> box) {
box.get();
}

The node (in AST) with capture binding does not have an error.
