Examples of org.hibernate.search.backend.LuceneWork

org.hibernate.search.backend.LuceneWork
Represent a Serializable Lucene unit work WARNING: This class aims to be serializable and passed in an asynchronous way across VMs any non backward compatible serialization change should be done with great care and publically announced. Specifically, new versions of Hibernate Search should be able to handle changes produced by older versions of Hibernate Search if reasonably possible. That is why each subclass susceptible to be pass along have a magic serialization number. NOTE: we are relying on Lucene's Document to play nice unfortunately @author Emmanuel Bernard @author Hardy Ferentschik @author Sanne Grinovero
