In class diagrams, should classes that implement the interface repeat the names of the methods?

Question

I create some UML diagrams, and I have a large number of classes that implement the interface.

Do these classes also need to list interface methods? That sounds pretty trivial, but will make the chart a lot easier if they don't.

Here is an image to show what I mean:

Any implementation of MyInterface requires method 1, method2 and method3 - can this be omitted?

I often refer to the Agile Modeling Class Diagram Guides . You will find the answer to this question in section 3 "Interfaces".

Quick answer: they can be ignored.
