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, Object, 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.

              java.lang.Object jsonValue,
              ConnectorTracker connectorTracker)

Parameters:

type - The expected return type

jsonValue - the value from the JSON

connectorTracker - the connector tracker instance for the UI

Returns:

A deserialized object

java.lang.Object serialize(T value,
                           ConnectorTracker connectorTracker)

Serialize the given object into JSON. Must be compatible with #deserialize(Object, connectorTracker) and the client side com.vaadin.client.communication.JSONSerializer

Parameters:

value - The object to serialize

connectorTracker - The connector tracker instance for the UI

Returns:
