Interface BrooklynMemento

All Superinterfaces:

Serializable

public interface BrooklynMemento
extends Serializable

Represents an entire persisted Brooklyn management context, with all its entities and locations. The referential integrity of this memento is not guaranteed. For example, an entity memento might reference a child entity that does not exist. This is an inevitable consequence of not using a stop-the-world persistence strategy, and is essential for a distributed brooklyn to be performant. Code using this memento should be tolerant of such inconsistencies (e.g. log a warning about the missing entity, and then ignore dangling references when constructing the entities/locations, so that code will not subsequently get NPEs when iterating over children for example).
