Element.ElementID of interfaceBlock

[MMiletic]

Hello guys,

do you know if there is a way to distinguish InterfaceBlock from "normal" blocks. If I get element type of something that is an interface block and from block it's both class (interfaceBlock.Type = class also block.Type = class)?

Thanks in advance

Did you check the stereotype?
If that's the same, check the classifier (using the ClassifierID)

Hey Geert,

thank you, Element.Stereotype gives info whether it's block or interface block.

Hello guys, is there a way to see where is connection from embeddedElement (port) going to, i.e. what is client?

Via its connectors?

I tried that. I have GUID of an block, .embeddedElements gives me ports in IBD and .connectors gives me all aggregations and generalizations in BDD, but I can't get the other end (ClientID) from connectors, but it shows the port on it's own instance.

This is code I am using:
element = eaRepository.GetElementByGuid(guid) # element in BDD, block
for i in range(element.EmbeddedElements.Count):
    currentEElement = element.EmbeddedElements.GetAt(i)
    print(str(i) + " " + currentEElement.Name)
    for j in range(currentEElement.Connectors.Count):
        currentEConnector = currentEElement.Connectors.GetAt(j)
        print("    " + str(j) + " " + eaRepository.GetElementByID(currentEConnector.ClientID).Name + " " + currentEElement.PropertyTypeName)

Depends on how you draw the connector. Try using the supplier instead. I for myself have a wrapper for connector yielding "other".

That works  Can you please describe this wrapper?

Well, I'm coding outside EA in Python. Would work with any other OO-like language, but not with that VB stuff (that's not a language but Babble; hence the B in in VB).

q.

[MMiletic]

Yeah, after reading your book I've also started working with Python So if you can please provide some draft I would be thankful

Would be a bit length to post the code. Since it's in some parts written for a customer I can not easily publish it. Maybe I find the time to share common parts on GitHub later. Anyhow, here's my wrapper (you need to create that from within a repository wrapper class whereever you return connectors. It makes use of other wrapper classes in a similar way.

Code: [Select]

class EAConnector(EAComObject):
    """ Wrapper to ease access to "opposite" elements of a connector """

    def __new__(cls, connector):
        if connector == None: return None
        instance = super(EAConnector, cls).__new__(cls)
        instance._comobj = connector
        instance._rep = Repository.Instance()
        instance._taggedValues = None
        return instance

    @property
    def taggedValues(self):
        if self._taggedValues == None:
            self._taggedValues = EATaggedValues(dummy, self._comobj.taggedValues)
        return self._taggedValues

    def other(self, objId):
        if isinstance(objId, EAElement):
            objId = objId.elementID
        elif isinstance(objId, EAPackage):
            objId = objId.element.elementID
        else:
            assert False, "Invalid use of other for %s" %objId
        otherId = self._comobj.supplierId if self._comobj.clientId == objId else self._comobj.clientId
        other = EAElement(self._rep.getElementByID (otherId))
        if other.type == "Package":
            package = self._rep.getPackageByGUID(other.elementGUID)
            return package
        else:
            return other

    def thisEnd(self, objId):
        if isinstance(objId, EAElement):
            objId = objId.elementID
        elif isinstance(objId, EAPackage):
            objId = objId.element.elementID
        else:
            assert False, "Invalid use of thisEnd for %s" %objId
        return  self._comobj.clientEnd if self._comobj.clientId == objId else self._comobj.supplierEnd

    def otherEnd(self, objId):
        if isinstance(objId, EAElement):
            objId = objId.elementID
        elif isinstance(objId, EAPackage):
            objId = objId.element.elementID
        else:
            assert False, "Invalid use of otherEnd for %s" %objId
        return  self._comobj.clientEnd if self._comobj.supplierId == objId else self._comobj.supplierEnd
