Is there a sleek way to map a default object in Hibernate?
For example, in this class, a Foo should always be able to return a Bar, whether it's custom defined for the Foo, or it comes from a default value that's stored in the database somewhere. Users of Foo should be able to set a custom Bar object in it, but they don't need write access to Bar - hence the reduced visibility. :
Code:
public Class Foo {
public Bar Bar {
get {
return CustomBar ?? DefaultBar;
}
}
public Bar CustomBar { get; set; }
protected Bar DefaultBar { get; private set; }
}
The thing I'm wondering about is how to hibernate map that DefaultFoo property. All the Bar classes should be able to get to that single DefaultFoo object. The only way I know how to do this in Hibernate is with a one-to-many mapping in Foo. (Foo containing one to many Bars)...this seems a little kludgy though, since there's always at most one Bar. Is there a better pattern for this type of behavior? TIA.
