Examples of DocumentExtractor

org.hibernate.search.engine.DocumentExtractor
Helper class to extract EntityInfos out of the QueryHits. @author Emmanuel Bernard @author John Griffin @author Hardy Ferentschik
org.hibernate.search.query.engine.spi.DocumentExtractor
DocumentExtractor is a traverser over the full-text results (EntityInfo) This operation is as lazy as possible: - the query is executed eagerly - results are not retrieved until actually requested {@link #getFirstIndex()} and {@link #getMaxIndex()} define the boundaries available to {@link #extract(int)}. DocumentExtractor objects *must* be closed when the results are no longer traversed. See {@link #close()} @author Emmanuel Bernard
