I had an object a of type A retieved from hibernate Set. I did some modification to the a. During this process, its hashCode changed. Then I would like to remove it from the Set. I removed it like this
net.sf.hibernate.collection.Set.remove(A). The hibernate Set can not find and remove the Object a! If I modify the type A so that its hashCode returns a constant value. No problem, hibernate Set can find and remove the Object. Below is the Set.remove() specification from Jdk 1.4. --------------------------------------------------- Removes the specified element from this set if it is present (optional operation). More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if the set contains such an element. Returns true if the set contained the specified element (or equivalently, if the set changed as a result of the call). (The set will not contain the specified element once the call returns.) ---------------------------------------------------- Notice that this spec never mentions anything about the hashCode. Moreover an object is only required to have a constant hashCode value provided no information used in equals comparisons on the object is modified. In hibernate current implementation, if a object is retrieved from Set and its hashCode is changed, there is no way to remove it from set. Any thoughts on this? Help is appreciated. jason __________________________________ Do you Yahoo!? Yahoo!
