Hello

I you can you please tell me how I can check if an operation has parameters?

I tried with

[query private hasNotParameterOperation(o : Operation) : Boolean = if o.ownedParameter -> isEmpty() then true else false endif/]

but, I failed. This will invoke from the other query to obtain all types of the parameters of all operations of the class

[query private getSetAllParamsTypeName(c : Class) : Set(String) = c.ownedOperation ->
select(o : Operation | not o.hasNotParameterOperation()) -> ownedParameter -> collect(type.name) -> asSet() /]

As you can see the final objective is to obtain all the parameters of a class, the middle Quiery put it because I saw that if he had an operation without parameters failed me.

In advance, thanks

Hi,

If you want to find if an operation has any parameters:
[for (anOperation : Operation | class.ownedOperation)]
[anOperation.ownedParameter->isEmpty()/]
[/for]

If you want to find all the parameters from all the operations of a class:
[class.ownedOperation-> union(class.getImplementedInterfaces().ownedOperation).owned Parameter/]

You would also need to look for the parameters from abstract method coming from the superclasses etc.

Thanks for your response.

My goal is to generate the "Imports " of class that I am modeling, regardless of its superclasses. I do the following:

[query private getSetAllParamsTypeNameSimples(c : Class) : Set(String) = getBagAllParams(c) -> collect(type.name) -> asSet() /]

[query private getBagAllParams(c : Class) : Bag(Parameter) = c.ownedOperation->ownedParameter -> asBag() /]

This works fine when all class operations with parameters in a class that has an operation without parameters neither input nor output gives me the following error:

Invalid result for expression getBagAllParams(c)->collect(temp5 : Parameter | temp5.type.name)->asSet() at line 219 in Module generateHelpers for query getSetAllParamsTypeNameSimples(Class). Last recorded value of self was org.eclipse.uml2.uml.internal.impl.ClassImpl@1fc89e9 (name: GccomMantUnidadesHelper, visibility: <unset>) (isLeaf: false, isAbstract: false) (isActive: false).

Hi,

First of all, this query should not work:
[query private getBagAllParams(c : Class) : Bag(Parameter) = c.ownedOperation->ownedParameter -> asBag() /]

It may be a typo of your message in this newsgroup but it should be:
[query private getBagAllParams(c : Class) : Bag(Parameter) = c.ownedOperation.ownedParameter -> asBag() /]

The message invalid result is returned if your query return a "null". The class "GccomMantUnidadesHelper" may be a class with methods without parameters. To solve your problem, you could try something like this:

[query private getBagAllParams(c : Class) : Bag(Parameter) = c.ownedOperation->select(ownedParameter->size() > 0).ownedParameter->asBag() /]

No it's ok. There is an implicit toCollection operation that I'm
proposing to reify as an explicit OclAny::oclAsSet() operation.

The first example is therefore just inefficient:

c.ownedOperation.oclAsSet()->collect(ownedParameter)-> asBag()

Thanks for your answers

Using the option that tells me Sthepane working fine. With the option of Edward It can't find the method "oclAsSet () ".

Again, thank you

Hi

There is no oclAsSet() method. I used it to clarify the implicit conversion.

I wrote that I'm proposing to reify it so that it can be used and
overloaded.
