Interface JSONSerializer<T>

All Known Implementing Classes:

DateSerializer

public interface JSONSerializer<T>

Implementors of this interface knows how to serialize an Object of a given type to JSON and how to deserialize the JSON back into an object.

The serialize(Object, ConnectorTracker) and deserialize(Type, JsonValue, ConnectorTracker) methods must be symmetric so they can be chained and produce the original result (or an equal result).

Each JSONSerializer implementation can handle an object of a single type.

This is the server side interface, see com.vaadin.client.communication.JSONSerializer for the client side interface.
