Hi,
I am creating Sequence Diagram using the Rhapsody API and I am working in C#. I could create "ClassifierRoles" for the classes using AddNewNodeForElement(). I am not able to create Messages. Can anyone share about how to do this?

Thanks,
Karthik.

Hello, I don't know if this can solve your problem, but I often use "addNewAggr" on many types of elements. It accepts any Rhapsody metaclass as parameters (including those which are not present in the API since they are just linked to stereotypes in the profiles). The name of the metaclass is the same as in the "Add New" right-clic menu.

PS: Have you tried "IRPCollaboration:
IRPMessage addMessage(IRPInterfaceItem interItem, java.lang.String actualParamList, IRPClassifierRole sender, IRPClassifierRole receiver)"
in which IRPInterfaceItem interItem is probably the operation that realizes the message.

Hi,

Milhouse is right. You can use IRPCollaboration as follow (with Java API) :


IRPCollaboration myColla;
IRPClassifierRole role1, role2;
IRPInterfaceItem myInterface, myInterface2, myInterface3;
IRPPackage pack = proj.addPackage("TestSequenceDiagramPack");
IRPClass component1 = pack.addClass("Class1");
IRPClass component2 = pack.addClass("Class2");
IRPOperation ope1 =((IRPClassifier)component1).addOperation("send");
IRPOperation ope2 =((IRPClassifier)component1).addOperation("Reply");
IRPOperation ope3 =((IRPClassifier)component1).addOperation("Compute");
myInterface = (IRPInterfaceItem)ope1;
myInterface2 = (IRPInterfaceItem)ope2;
myInterface3 = (IRPInterfaceItem)ope3;
myColla = proj.getNewCollaboration();
role1 = myColla.addClassifierRole("component1", (IRPClassifier)component1);
role2 = myColla.addClassifierRole("component2", (IRPClassifier)component2);

IRPMessage mess = myColla.addMessage(myInterface, null, role1, role2);
IRPMessage mess1 = myColla.addMessage(myInterface3, null, role1, role1);
IRPMessage mess2 = myColla.addMessage(myInterface2, null, role2, role1);

myColla.generateSequence("theSequenceDiagram", pack);

The last instruction "draws" the diagram.
