Sequence diagram for only one class
I have one java class which has all the logic in it. It has 10 methods. Everything happens in this class. How can I modell it? Or how can I show its functionality? I have tried a sequence diagramm but it only has calls to itself. 

What is the best solution to modell it? Or to explain how the class works?
