public interface ProxySerializer
Serializes graphs of EntityProxy objects. A ProxySerializer is associated
with an instance of a ProxyStore when it is created via
RequestFactory.getSerializer(ProxyStore).
The EntityProxy.stableId() of non-persisted (i.e. newly
created) EntityProxy instances
are not stable.
To create a self-contained message that encapsulates a proxy:
RequestFactory myFactory = ...; MyFooProxy someProxy = ...; DefaultProxyStore store = new DefaultProxyStore(); ProxySerializer ser = myFactory.getSerializer(store); // More than one proxy could be serialized String key = ser.serialize(someProxy); // Create the flattened representation String payload = store.encode();To recreate the object:
ProxyStore store = new DefaultProxyStore(payload); ProxySerializer ser = myFactory.getSerializer(store); MyFooProxy someProxy = ser.deserialize(MyFooProxy.class, key);If two objects refer to different EntityProxy instances that have the same stableId(), the last mutable proxy encountered will be preferred, otherwise the first immutable proxy will be used.
