Interface RebindSupport<T extends Memento>

All Known Implementing Classes:

AbstractBrooklynObjectRebindSupport, BasicCatalogItemRebindSupport, BasicEnricherRebindSupport, BasicEntityRebindSupport, BasicFeedRebindSupport, BasicLocationRebindSupport, BasicManagedBundleRebindSupport, BasicPolicyRebindSupport

public interface RebindSupport<T extends Memento>

Supporter instance for behaviour related to rebinding a given entity/location/policy. For example, the brooklyn framework may call entity.getRebindSupport().getMemento() and persist this using a BrooklynMementoPersister. Later (e.g. after a brooklyn restart) a new entity instance may be created and populated by the framework calling entity.getRebindSupport().reconstruct(rebindContext, memento).

Method Summary

Modifier and Type	Method and Description
void	addEnrichers(RebindContext rebindContext, T Memento)
void	addFeeds(RebindContext rebindContext, T Memento)
void	addPolicies(RebindContext rebindContext, T Memento)
T	getMemento() Creates a memento representing this entity's current state.
void	reconstruct(RebindContext rebindContext, T memento) Reconstructs this entity, given a memento of its state.

Method Detail

getMemento

T getMemento()

Creates a memento representing this entity's current state. This is useful for when restarting brooklyn.

reconstruct

void reconstruct(RebindContext rebindContext,
                 T memento)

Reconstructs this entity, given a memento of its state. Sets the internal state (including id and config keys), and sets the parent/children/locations of this entity. Implementations should be very careful to not invoke or inspect these other entities/locations, as they may also be being reconstructed at this time. Called during rebind, after creation and before the call to start management.

addPolicies

void addPolicies(RebindContext rebindContext,
                 T Memento)

addEnrichers

void addEnrichers(RebindContext rebindContext,
                  T Memento)

addFeeds

void addFeeds(RebindContext rebindContext,
              T Memento)
