[EuGENia] Node label from attribute of contained class [message #23406] Sun, 26 July 2009 10:59 Go to next message

Hello,

Below is the snippet from the .emf file. The output of the below code
resembles to the UML Object diagram where ObjectTemplateExp is Object
and PropertyTemplateExp is the attribute in the object.

I want to fetch the value of attr "name" from VariableExp class and show
it as a label for ObjectTemplateExp node. Also, want to fetch the name
of the referred class so that the label pattern looks like "variable :
(name of referredClass)"

Same for the label of PropertyTemplateExp "(name of referredProperty) =
value"

Any help/pointers to help will be highly appreciated.

code:

@gmf.node(label="variable.name")
class ObjectTemplateExp extends ExtendedOclExp {
val VariableExp variable;

@gmf.compartment(layout="list", collapsible="false")
val PropertyTemplateExp[*] propertyTemplates;
ref EClass referredClass;
}

@gmf.node(label="name", label.icon="false", figure="rectangle")
class PropertyTemplateExp {
val ExtendedExp value;

@gmf.link(target.decoration="arrow")
ref ecore.EStructuralFeature referredProperty;
}

class VariableExp {
!unique !ordered attr String name;
}



Thanks,
Mihir

Just to add further to my last post. I also want a simple reference link
to link a instance of ObjectTemplateExp to the other instance of
ObjectTemplateExp if the type of the referredProperty (in instance of
PropertyTemplateExp) is of type EReference.

Hope this all makes sense.

Thanks,
Mihir

Hi Mihir,

In this case, you'd have to add a new derived volatile and transient
attribute, and set it as the label of your ObjectTemplateExp like this:

@gmf.node(label="label")
class ObjectTemplateExp extends ExtendedOclExp {
val VariableExp variable;

derived transient volatile attr String label;

@gmf.compartment(layout="list", collapsible="false")
val PropertyTemplateExp[*] propertyTemplates;
ref EClass referredClass;
}

When you generate the EMF code, you'll need to go into the generated
ObjectTemplateExpImpl.getLabel() method, turn it to @generated NOT and
make it return variable.name (instead of throwing an unsupported
operation exception).

Cheers,
Dimitris

Hi Mihir,

I'm not sure I understand this :( Do you need links to be automatically
created between unlinked objects when a certain condition is satisfied?

Cheers,
Dimitris

Hello Dimitris,

Many thanks for your quick reply. I'll try and implement this and get
back to you soon. I don't if it is a feasible question but can we make
it work without adding that extra derived transient volatile attribute??
Because, the thing is I don't want to make any changes in the metamodel.
I'll still try your this suggested technique.

Thanks,
Mihir

Hi Dimitris,

Thanks for you quick reply. I was meant to add the link manually from
tools palette. But, it would be great to achieve your idea as well.. ;)
Awaiting for your input. :)

Thanks,
Mihir

So you actually want to prevent users from creating a link between the
two objects if the condition is not satisfied. I know that this is
possible using OCL but to be honest, I haven't ever played with this
feature. I'll look into this in the next few days and get back to you.
If by any chance you manage to make any progress with this before I do,
it'd be great if you could report back with the solution you've found.

It should be possible to do this in a batch mode using EWL. See

http://www.eclipse.org/gmt/epsilon/doc/ewl

and the example in

http://www.eclipse.org/gmt/epsilon/cinema/#GMFWizards2

for more details.

Hi Mihir,

I don't know if it is possible to do this without adding that extra
attribute. Another question for the GMF newsgroup it seems ;)

OK Dimitris,

I'm looking at the links sent by you. And I'll update you if I found
anything.

Meanwhile, I've this 1 stupid question. It is related to GMF but, still
asking if you know any solution for this. The description of question is
once I've generated all the codes for the editor and tested it. Then, I
update the definition in .emf file and generate all the required codes.
Now if I've removed anything from the .emf ( for example I remove a link
annotation) and then generate the code I get error in the generated
code. If I delete all the code and regenerate it, it works fine. Just
wondering if you have any solution for this.

Cheers,
Mihir

Hi Mihir,

This is reasonable as the generator doesn't attempt to delete files that
it generated in a previous run but are not necessary any more.

Cheers,
Dimitris

So I'll have to delete the generated code before generating new code.
I'll have to keep track if I've made any changes in the generated code
and make those changes again. Arghhh!!

Anyways thanks a million for your quick response. I'm newbie in this
group and even to the GMF stuffs.

Cheers,
Mihir

Hello Dimitris,

Sorry for delayed reply. I'd gone out for a while.

I've implemented a derived attribute and generated all the code as told
by you. But, what I saw is that it is same as adding a new simple
attribute to the class because the generated code seems like the same as
that generated for simple attribute. Below is the code that is
generated. I can't find any code throwing unsupported operation exception.


public String getLabel() {
return
(String)eGet(Moment2transformationPackage.Literals.OBJECT_TE MPLATE_EXP__LABEL,
true);
}

public void setLabel(String newLabel) {
eSet(Moment2transformationPackage.Literals.OBJECT_TEMPLATE_E XP__LABEL,
newLabel);
}


Cheers,
Mihir

Hi Mihir,

Could you please check again that you have all 3 modifiers in your label
attribute and that you have regenerated the .ecore from the .emf and
reloaded the .genmodel? (if necessary, please delete the .genmodel and
regenerate it).

Cheers,
Dimitris

Hi Dimitris,

I did tried this couple of times. Deleted all the generated code and all
those model files. Regenerated everything.. still it generates same code. :S

Sorry for delayed reply.

Just to add further to my last post. I also want a simple reference link
to link a instance of ObjectTemplateExp to the other instance of
ObjectTemplateExp if the type of the referredProperty (in instance of
PropertyTemplateExp) is of type EReference.

Hope this all makes sense.

Thanks,
Mihir

Hi Mihir,

In this case, you'd have to add a new derived volatile and transient
attribute, and set it as the label of your ObjectTemplateExp like this:

@gmf.node(label="label")
class ObjectTemplateExp extends ExtendedOclExp {
val VariableExp variable;

derived transient volatile attr String label;

@gmf.compartment(layout="list", collapsible="false")
val PropertyTemplateExp[*] propertyTemplates;
ref EClass referredClass;
}

When you generate the EMF code, you'll need to go into the generated
ObjectTemplateExpImpl.getLabel() method, turn it to @generated NOT and
make it return variable.name (instead of throwing an unsupported
operation exception).

Cheers,
Dimitris

Hi Mihir,

I'm not sure I understand this :( Do you need links to be automatically
created between unlinked objects when a certain condition is satisfied?

Cheers,
Dimitris

Hello Dimitris,

Many thanks for your quick reply. I'll try and implement this and get
back to you soon. I don't if it is a feasible question but can we make
it work without adding that extra derived transient volatile attribute??
Because, the thing is I don't want to make any changes in the metamodel.
I'll still try your this suggested technique.

Thanks,
Mihir

Hi Dimitris,

Thanks for you quick reply. I was meant to add the link manually from
tools palette. But, it would be great to achieve your idea as well.. ;)
Awaiting for your input. :)

Thanks,
Mihir

So you actually want to prevent users from creating a link between the
two objects if the condition is not satisfied. I know that this is
possible using OCL but to be honest, I haven't ever played with this
feature. I'll look into this in the next few days and get back to you.
If by any chance you manage to make any progress with this before I do,
it'd be great if you could report back with the solution you've found.

> But, it would be great to achieve your idea as well.. ;)

It should be possible to do this in a batch mode using EWL. See

http://www.eclipse.org/gmt/epsilon/doc/ewl

and the example in

http://www.eclipse.org/gmt/epsilon/cinema/#GMFWizards2

for more details.

Hi Mihir,

I don't know if it is possible to do this without adding that extra
attribute. Another question for the GMF newsgroup it seems ;)

OK Dimitris,

I'm looking at the links sent by you. And I'll update you if I found
anything.

Meanwhile, I've this 1 stupid question. It is related to GMF but, still
asking if you know any solution for this. The description of question is
once I've generated all the codes for the editor and tested it. Then, I
update the definition in .emf file and generate all the required codes.
Now if I've removed anything from the .emf ( for example I remove a link
annotation) and then generate the code I get error in the generated
code. If I delete all the code and regenerate it, it works fine. Just
wondering if you have any solution for this.

Cheers,
Mihir

Hi Mihir,

This is reasonable as the generator doesn't attempt to delete files that
it generated in a previous run but are not necessary any more.

So I'll have to delete the generated code before generating new code.
I'll have to keep track if I've made any changes in the generated code
and make those changes again. Arghhh!!

Anyways thanks a million for your quick response. I'm newbie in this
group and even to the GMF stuffs.

Cheers,
Mihir

Hello Dimitris,

Sorry for delayed reply. I'd gone out for a while.

I've implemented a derived attribute and generated all the code as told
by you. But, what I saw is that it is same as adding a new simple
attribute to the class because the generated code seems like the same as
that generated for simple attribute. Below is the code that is
generated. I can't find any code throwing unsupported operation exception.


public String getLabel() {
return
(String)eGet(Moment2transformationPackage.Literals.OBJECT_TE MPLATE_EXP__LABEL,
true);
}

public void setLabel(String newLabel) {
eSet(Moment2transformationPackage.Literals.OBJECT_TEMPLATE_E XP__LABEL,
newLabel);
}


Cheers,
Mihir

Hi Mihir,

Could you please check again that you have all 3 modifiers in your label
attribute and that you have regenerated the .ecore from the .emf and
reloaded the .genmodel? (if necessary, please delete the .genmodel and
regenerate it).

Cheers,
Dimitris

Hi Dimitris,

I did tried this couple of times. Deleted all the generated code and all
those model files. Regenerated everything.. still it generates same code. :S

Sorry for delayed reply.

Cheers,
Mihir

Hi Mihir,

Strange! Could you please send me your metamodel so that I can have a look?

Cheers,
Dimitris
