Hello,
i'm curios about a special detail within the operation.
First a simple use case:
class A implements I
{
public void test(){...}
}
interface I
{
public void test();
}
If i understand the UML2 model correctly, the operation test of class A should have a interface set, pointing to I.
But what if i have two different interfaces:
class A implements I1,I2
{
public void test(){...}
}
interface I1
{
public void test();
...
}
interface I2
{
public void test();
...
}
How should this be represented with the UML2 model?
With regards
Dennis Keßler

Dennis,
Note that, as part of "realizing" an interface in UML, the realizing
classifier (class in this case) must define operations that conform to those
of its realized interface(s). So I would expect this to be represented
something like this:
<packagedElement xmi:type="uml:Interface"
xmi:id="_4pbdUAZuEd2Gt5apY3MUbw" name="I1">
<ownedOperation xmi:id="_8IDgUAZuEd2Gt5apY3MUbw" name="test"/>
</packagedElement>
<packagedElement xmi:type="uml:Interface"
xmi:id="_93Nw0AZuEd2Gt5apY3MUbw" name="I2">
<ownedOperation xmi:id="__bNTIAZuEd2Gt5apY3MUbw" name="test"/>
</packagedElement>
<packagedElement xmi:type="uml:Class" xmi:id="_BGM1UAZvEd2Gt5apY3MUbw"
name="A" clientDependency="_cFZmsAZvEd2Gt5apY3MUbw _eTtRUAZvEd2Gt5apY3MUbw">
<interfaceRealization xmi:id="_cFZmsAZvEd2Gt5apY3MUbw"
supplier="_4pbdUAZuEd2Gt5apY3MUbw" client="_BGM1UAZvEd2Gt5apY3MUbw"
contract="_4pbdUAZuEd2Gt5apY3MUbw"/>
<interfaceRealization xmi:id="_eTtRUAZvEd2Gt5apY3MUbw"
supplier="_93Nw0AZuEd2Gt5apY3MUbw" client="_BGM1UAZvEd2Gt5apY3MUbw"
contract="_93Nw0AZuEd2Gt5apY3MUbw"/>
<ownedOperation xmi:id="_QAK6QAZvEd2Gt5apY3MUbw" name="test"/>
</packagedElement>
That is, the class A would own an operation that conforms to the test
operation from both I1 and I2.
