public abstract class CachableNugget
extends Nugget

The super class of all CachableNugget.

The Nugget class is the base class for all Nugget objects. Nuggets provide entities access to authenticated or non-authenticated back-end services. It is important to remember that Nuggets can only be instantiated through the createNugget() method on Entity. This ensures the all nugget instances are associated to an entity in the system.

Nuggets are used to access different types of services and as such different Nugget classes may have very different programming interfaces. This class provides the base CachableNugget interface.

A CachableNugget will instantiated and attached to the associated Entity object. It will not be instantiated again unless the invoker explicitly release the Nugget instance from the Entity.
