Interface ProxySerializer

@Deprecated
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();
 

 ProxyStore store = new DefaultProxyStore(payload);
 ProxySerializer ser = myFactory.getSerializer(store);
 MyFooProxy someProxy = ser.deserialize(MyFooProxy.class, key);
 

RequestFactory has moved to com.google.web.bindery.requestfactory. This package will be removed in a future version of GWT.
