Examples of javax.persistence.EntityManager.unwrap()

javax.persistence.EntityManager.unwrap()
Return an object of the specified type to allow access to the provider-specific API. If the provider's EntityManager implementation does not support the specified class, the PersistenceException is thrown. @param cls the class of the object to be returned. This isnormally either the underlying EntityManager implementation class or an interface that it implements. @return an instance of the specified class @throws PersistenceException if the provider does notsupport the call.

            List<WeakReference<EntityManager>> xpcs = SFSBXPCMap.getINSTANCE().getXPC(handle);
            if (xpcs == null)
                continue;
            for (WeakReference<EntityManager> xpc_ref : xpcs) {
                EntityManager xpc = xpc_ref.get();
                if (xpc != null && xpc.unwrap(EntityManagerMetadata.class).getScopedPuName().equals(puScopedName)) {
                    return xpc;
                }
