ExtensibleObject is the interface from which all objects that reside in the registry are derived. The methods of this interface provide for the association with a registry object of attributes that are not explicitly defined in the JAXR API. An ExtensibleObject may have any number of these attributes, which are represented by the Slot interface. Slot s are created and added by the JAXR provider and may also be used by application code, although not all JAXR providers will store application-created Slot s in the registry.

Slot s can be added to an ExtensibleObject either singly using the addSlot( ) method or as a group by calling addSlots( ) ; they can be removed using removeSlot( ) or removeSlots( ) . Both of these methods use the name of the Slot as the key. The getSlot( ) method locates a Slot given its name and returns null if no slot with the supplied name is associated with the ExtensibleObject . Finally, the getSlots( ) method returns a Collection containing all of an object's Slot s.
