Examples of org.infinispan.atomic.DeltaAware

org.infinispan.atomic.DeltaAware
This interface allows the extraction of {@link Delta}s.
Implementations would be closely coupled to a corresponding {@link Delta} implementation, since {@link Delta#merge(DeltaAware)} would need to know how to recreate this instance of DeltaAware if needed.
Implementations of DeltaAware automatically gain the ability to perform fine-grained replication in Infinispan, since Infinispan's data container is able to detect these types and only serialize and transport Deltas around the network rather than the entire, serialized object.
Using DeltaAware makes sense if your custom object is large in size and often only sees small portions of the object being updated in a transaction. Implementations would need to be able to track these changes during the course of a transaction though, to be able to produce a {@link Delta} instance, so this too is a considerationfor implementations.
