Java: Interface with new keyword how is that possible?

Question

I was reading some sourcecode from Java libraries, and I am confused here;

This code is from Document.java in jaxb library, and ContentVisitor is an Interfac

Answer 1

It is inline interface implementation.Here the idea is to have the compiler generate an anonymous class that implements the interface. Then for each method defined in the interface you can (optionally) provide a method with a suitable signature that will be used as the implementation of the interface's method.

It is the new Oxygene syntax, added to the language to allow Oxygene programmers to work with these interface-based events in much the same way as Java programmers do.
