Hi All,
I have got an attribute in my automatically generated Metamodel, to be of
type NonNegativeInteger (or 'class java.math.BigInteger').
Now I try to assign some value to it but it gives me the errors like
Ingeter can't be mapped to BigInteger. See it:
SEVERE: ****** BEGIN Stack Trace
SEVERE: message: cannot set feature myML!BDefType.maxMasters to value 5
SEVERE: exception:
SEVERE: The value of type 'class java.lang.Integer' must be of type 'class
java.math.BigInteger'
java.lang.ClassCastException: The value of type 'class java.lang.Integer'
must be of type 'class java.math.BigInteger'
I can't even assign it value directly. Is there any other method to give
values to such datatypes or ATL doesn't support them all. what abt the
setRefValue() function?
Will be waiting for suggestions,
Regards,
-aamir-

You said that I can set such a value, How? have u got any example? Using
setValueRef() or anything else? I mean for now I only want the solution,
have u got any solution at all? (No matter how odd it is), other than
waiting for the next release of ATL....:)
Hope to hear u soon urs,
thanks alot,

Can you be more explicit. Two things u state in ur mail.
To change the metamodel, I already said an "automatically generated
metamodel" so I m unable to change it and even if I am able to do so, who
will be doing it for 100+ attributes and that also, each time a new
version is released !!!
I couldn't grab ur second point correctly. do u want to say that I must
beware of the wrong values assigned, through the code? But my code error
clearly says:
SEVERE: message: cannot set feature myML!BDefType.maxMasters to value 5
SEVERE: exception: SEVERE: The value of type 'class java.lang.Integer'
must be of type 'class java.math.BigInteger'
so, the error is not due to that. May be u mean something else! I just
long some way, maybe to convert my value '5' to bigInteger and then pass
it. I mean, in all terms the BigInteger is the superset of Integer, then
why not be compatible???
Thanks for the reply and hope to see ur comments soon.
Ciao,

Hello!
Does anyone have a solution for this problem? I want to assign a value
to my output model, but as it seems to be of the type
"Java.math.BigInteger", I always get error messages like this one:
"Caused by: java.lang.ClassCastException: The value of type 'class
java.lang.Integer' must be of type 'class java.math.BigInteger'"
Aamir seems to have had the same problem, have you got any solution?
Does ATL support BigIntegers now? Is there a simple way to transform
Integers or Strings to BigIntegers?
I hope, someone answers,
Manu

Hello,
There is at this time no way to set those types in ATL.
We are studying the possibility to provide a core extensibility for this
issue, in order to easily allow users to define theyre own types adapters.
For the moment, you can use the old way (quite hard but possible),
referring to that use case :
http://www.eclipse.org/m2m/atl/usecases/UML2AnyLogic/
In it you will find a custom model handler which allows the use of
specific data types.
Best regards,
William
