Examples of org.infinispan.atomic.Delta.merge()

org.infinispan.atomic.Delta.merge()
Merge the current Delta instance with a given {@link DeltaAware} instance, and return a coherent and complete{@link DeltaAware} instance. Implementations should be able to deal with null values passed in, or values of adifferent type from the expected DeltaAware instance. Usually the approach would be to ignore what is passed in, create a new instance of the DeltaAware implementation that the current Delta implementation is written for, apply changes and pass it back. @param d instance to merge with, or null if no merging is needed @return a fully coherent and usable instance of DeltaAware which may or may not be the same instance passed in

         o = e.setValue(value);
