Method Detail

id

protected Object id(Object o)

Returns the globally unique, logical id for the provided object, or null, if it has no id (yet), or AbstractIdentityFixer.ANONYMOUS is this object is of value type. o may be null, point to an ordinary object or to an array.

The ID objects returned by this method must be value-comparable using equals (which implies that hashCode must be overridden as well). To permit garbage-collection, ids referring to the object they identify should do so with weak references.

Overrides:

id in class HibernateProxyAwareIdentityFixer

Parameters:

o - The object for which a globally unique, logical id will be returned

Returns:

A globally unique, logical ID object for the given object
