Hi,

I am a beginner and playing with the OCL, and trying to identify identical model elements using following query.

context uml::Model
inv: Actor.allInstances()->exists(a1,a2:Actor| a1<>a2 and a1.name= a2.name)

It returns me true result, this means that two actor with same name are present in the model.

now the next step , I want output that query should also show me the name of the identical actors, for this if I apply select operation on exists but it complains, any suggestion how can I get the value of those identical elements.

Thanks in advance,
pokojo

Hi, pokojo,

Try something like this:

context uml::Model
def: findSimilarActors() : Set(Actor) =
Actor.allInstances()->select(a |
Actor.allInstances()->exists(b | a <> b and a.name =
b.name))

Then if you need the names, do:

getModel().findSimilarActors().name->asSet()

HTH,

Christian

Hi,

I am a beginner and playing with the OCL, and trying to identify identical model elements using following query.

context uml::Model
inv: Actor.allInstances()-&gt;exists(a1,a2:Actor| a1&lt;&gt;a2 and a1.name= a2.name)

It returns me true result, this means that two actor with same name are present in the model.

now the next step , I want output that query should also show me the name of the identical actors, for this if I apply select operation on exists but it complains, any suggestion how can I get the value of those identical elements.

Thanks in advance,
pokojo

Hi, pokojo,<BR>

Try something like this:<BR>
<BR>
context uml::Model<BR>
def: findSimilarActors() : Set(Actor) =<BR>
&nbsp;&nbsp;&nbsp; Actor.allInstances()-&gt;select(a |<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Actor.allInstances()-&gt;exists(b | a &lt;&gt; b and a.name = b.name))<BR>

Then if you need the names, do:<BR>
<BR>
&nbsp;&nbsp;&nbsp; getModel().findSimilarActors().name-&gt;asSet()<BR>

Hi,

I am a beginner and playing with the OCL, and trying to identify identical model elements using following query.

context uml::Model
inv: Actor.allInstances()-&gt;exists(a1,a2:Actor| a1&lt;&gt;a2 and a1.name= a2.name)

It returns me true result, this means that two actor with same name are present in the model.

now the next step , I want output that query should also show me the name of the identical actors, for this if I apply select operation on exists but it complains, any suggestion how can I get the value of those identical elements.

Thanks in advance,
pokojo

Hi, pokojo,

Try something like this:

context uml::Model
def: findSimilarActors() : Set(Actor) =
Actor.allInstances()->select(a |
Actor.allInstances()->exists(b | a <> b and a.name =
b.name))

Then if you need the names, do:

getModel().findSimilarActors().name->asSet()

HTH,
