Interface Associated<T>

Type Parameters:
T - the type of associated key
All Known Subinterfaces:
KeyAssociation<T>

AbstractPersistenceManager.AbstractPersistentStore.BatchTask, AbstractPersistenceManager.AbstractPersistentStore.DeleteExtentTask, AbstractPersistenceManager.AbstractPersistentStore.OpenTask, AbstractPersistenceManager.BatchTasks, CompositeKey, NonBlockingFiniteStateMachine.Task
public interface Associated<T>
The Associated interface facilitates the creation of a very generic equivalence relation between different objects and allows to group them based on the equality of the "association key" object returned by the getAssociatedKey() method.

      T getAssociatedKey()
      Determine the host key (or base) object to which this object is associated.

      Note: It's expected that the returned object is suitable to be used as an immutable identity (e.g. a key in a Map).
      Note 2: Circular associations are not permitted.

      Returns:
      the host key that for this object, or null if this object has no association
