the class StateManager method activate.

/**
 * This operation activates an object. Activation of an object may entail
 * loading its passive state from the object store and unpacking it into the
 * memory resident form, or it may simply be a no-op. Full activation is
 * only necessary if the object is currently marked as being PASSIVE (that
 * is, the object was constructed as being of type ANDPERSISTENT with an
 * existing uid and has not already been activated). Objects that are not of
 * type ANDPERSISTENT or are persistent but have not yet been saved in an
 * object store (so-called new persistent objects) are unaffected by this
 * function. Returns false if PASSIVE object cannot be loaded from object
 * store, true otherwise.
 *
 * @return <code>true</code> on success, <code>false</code> otherwise.
 * @see com.arjuna.ats.arjuna.objectstore.ObjectStore
