How to get domain from context

[akira]

Hi, i'm getting my context this way: ObjectContext context =  
DataContext.getThreadObjectContext(). How to know the domain that the  
context is using? If i get context as a DataContext type i can obtain  
the domain using : getParentDataDomain().getName() right? On my app i  
have to change the domain under certain circumstancies and on my code  
i'm trying to do something like this:
ObjectContext context = DataContext.getThreadObjectContext()
if (context.getDomain() == domainToQueryNow) {
 return context;
} else {
 DataContext.createDataContext(domainToQueryNow);
}
TIA.
