Hi,
I have a model B which has the containment hierarchy.
BType {
name:String,
chidlObject1ref:childObject1Type,
childlObject2ref:childObject2Type
}
ChidObject1Type {
name:String,
.....
}
ChildObject2Type {
name:string,
....
}
where childObject1Type and childObjectType are objectTypes defined in the
same package where BType is defined.
And another model A which should be
AType {
uri:String,
bRef: BTypeReference
operation; EnumTypevalue
}
Where AType is in different package. This is kind of query support.
I need to write a model B But the A is already existing, When instanciating
A Object, depending the operation value A instance should have the children
which are of the children of BType Object instance.I am not sure this can be
possible in EMF or not. Some help is appriciated.
to be more specific.,
BObectInstance is like this,
Binstance {
"foo",
childObject1ref {
"bar"
}
chidlObject2ref {
"junk"
}
}
AInstnace {
uri="auri"
bref = "BInstance"
operation="childobject1typeonly"
<bar>
<if bar has child elements then those child elements name should be child
elements here>
/** if operation="childobject2typeonly" then all the content should
childobject2type elements NOT the childobject1type**/
}
Thanks
Suresh Subramanian

Suresh,
I can't say I've entirely understood what you're describing. Your model
will likely have to be general enough to allow even ill formed instance
and then you'll have to define constraints to diagnose those bad forms.
You'll be able to specialize the editor to prevent the user from
creating such bad forms.

Thanks Ed for your response. Probably i need to explain more clearly.
following is the fragment. of model Object Type BType i referred in my
previous mail
<ManagedResource name="mr1>
<Config Data name="configdata1"> /** this is the
childObject1Type i am referring **/
<attribute name ="attribute1"/>
<attribute name="attribute2"/>
</Config Data>
</ManagedResource>
It is entirely in different Resource.
In another resouce in AType if i don't specify any thing in operation
default behaviour and create A instance in my editor
<AInstance uri="some text", bref="mr1', operation="defalut"/>
then <AInstance should looklike and saved as follows.
<AInstance uri="some text" bref="mr1" operation="default">
<mr1>
<configdata1> /*child object contents need to be displayed.*/
<attribute1/>
</attribute2/>
</configdata1>
</AInstance>
If the operation is different such that other object need to be displayed,
then <mr1> content shouldnot have <configdata1>, instead it should be the
content matching with the filtering criterio specified in the operation.
After that similar to XML editor if i need add another node of any type in
any node in the above, i should be able to do that. I am not sure how to
define this model for A instance. Is it possible first of all.
hope this explains better.
Thanks,
Suresh Subramanian

Not so much no...
You can have features of type EObject, which in XML Schema you'd define
as xsd:anyType. Such features can contain anything.
