如何在状态机图中准确获取元素的类型Enterprise Architect

Question

I want to find exactly type of element in StateMachine diagram (Initial State, Choice, EntryPoint, ExitPoint...) using EA.Automation interface. see the pictures below:

• Example1
• Example2

I used the code snippet below:

void GetRealTypeOfNodes(EA.Diagram diagram)
    {
        var objects = diagram.DiagramObjects;
        foreach(EA.DiagramObject obj in objects)
        {
            EA.Element elem = Repository.GetElementByID(obj.ElementID); 

            MessageLogger.log(elem.Type, obj.ObjectType.ToString(), elem.Name, obj.GetType().ToString());
        }
    }

but what I get is:

• type of elements: "StateNode" - not as expected, Eg: Initial State or Choice

Could you help me to get what exactly I want?

Answer 1

You need to inspect Element.SubType :

• 11 = decision
• 3 = initial

This might be documented somewhere in EA's help, or it might not. Issue the query

SELECT name, ntype FROM t_object

in the SQL scratch pad. This will return the subType in ntype and you can find out missing ones.

According to my Inside book, StateNode s can take the values 3, 4, 10, 11, 12, 13, 14, 100 and 101 as SubType . But I have not listed, which is which.
