This is still my first days of working with AndroMDA, and with a modelling tool
other than for communication purposes, so you will have to excuse if my
questions are not precisely defined.
I am trying to create an object model of my business domain. In particular, I
am modeling the trading of financial instruments. The particular error below is
occuring when i have a reference from an Entity to an Embedded Value which is
an abstract Order of which there are generalizations of LimitOrder,
StopLossOrder, FixingOrder etc... The abstract Order does not have any methods
or attributes as yet... Each of the generalizations are also Embedded Values.
The resulting code in the Order getInstance(Order otherObject) method is
completely wrong and will not compile. The generated method in the Order.java
class looks like:
/**
* Creates a new instance from other Order instance.
*/
public static Order newInstance(Order otherObject)
{
if (otherObject != null)
{
return newInstance( }
return null;
}
You did not mention any possible cause to this compilation error in your
response. Do you have any ideas as to what I may be doing wrong?
In relation to the second question, I was simply wondering whether there was
any difference in the generated code if i modeled a reference from an Entity to
an Embedded Value using an attribute as opposed to a reference. Are both
supported in the Hibernate cartridge?
Finally, the third question related to the first point really... I did model a
Currency interface which is implemented by the two Embedded Values :
SingleCurrency and a CurrencyCouple. Both reflect the same behaviour and
therefore share the same interface (now I might be heading into the psm arena
as you suggested)... I have created an association from an Embedded Value
(Rate) to the Currency interface and get errors trying to validate the model
when running AndroMDA... I am interested in how this could better be handled or
whether it is possible to handle it already...
