How would I persist class A below? C and D have a composite primary key in the database. The primary key for C is innermostOneKey and referenceToOutermostKey. The primary key for D is innermostOneKey and referenceToOutermostKey.
My understanding is that with ManageableHashMap, when loading from the database the key in the Map is set to the primary key. Clearly that won't work with a composite key. I'd really rather not use a reference table however if at all possible. The other alternative is to use ManageableArrayLists instead of Maps. This has other side-effects however which lead to a slightly unclean API. I'd like to avoid that if possible, but will resort to it if it is the simplest solution. Is there any way to do this? --- class A { Map outermost; } class B { Integer outermostKey; Map innermostOne; Map innermostTwo; } class C { Integer innermostOneKey; Integer outermostKey; ... } class D { Integer innermostTwoKey; Integer outermostKey; ... } class Main { public static void main(String[] args) { A a = new A(); B b = new B(); C c = new C(); D d = new D(); c.outerMostKey = b.outermostKey; d.outerMostKey = b.outermostKey; b.innermostOne.put(c.innermostOneKey, c); b.innermostTwo.put(d.innermostTwoKey, d); a.outermost.put(b.outermostKey, b); ... } } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
