Does IntelliJ IDEA have a Create Wrapper code generator

Question

If I have an interface with a few methods. Sometimes I need to create a new implementation of the interface which wraps another instance of the interface and delegates most of the methods to the wrapped instance. Then I would change a couple of the implementations, maybe not delegating them.

A classic example would be the Collections.unmodifiableXXX() methods in the JDK which block access to the modification methods.

Does IntelliJ have any code assistance that will generate a delegate implementation of the interface and then I can just tweak a couple of methods?

Answer 1

You can do it in two stages. First implement the interface and then introduce delegation

Answer 2

Code|Delegate Methods
