Class GadgetState

java.lang.Object

com.atlassian.gadgets.GadgetState

All Implemented Interfaces:

DashboardItemState, Serializable

@Immutable
public class GadgetState
extends Object
implements DashboardItemState, Serializable

An immutable extension of DashboardItemState. GadgetState state extends the DashboardItemState with:

• a spec URI, indicating where the gadget spec is located
• a Map of the user preference values

GadgetState objects should be built using the builders. At a minimum, the GadgetId and spec URI are required.

By doing a static import of the gadget(GadgetId) method, you can create a GadgetState object with:

     GadgetState state = gadget(GadgetId.from(1000)).specUri("http://gadget/url").build();
 

Or you can build a new GadgetState object from an existing one with:

     GadgetState state = gadget(originalState).color(color1).build();
 

GadgetState implements the Serializable marker interface. Serialization is only implemented so that GadgetState objects may be distributed among remote systems that might be sharing a cache or need to transfer GadgetStates for other reasons. Serialization is not meant to be used as a means of persisting GadgetState objects between JVM restarts.
