org.hibernate.search.query.engine.impl.DocumentExtractorImpl

All Implemented Interfaces:

DocumentExtractor

public class DocumentExtractorImpl
extends Object
implements 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 #getFirstIndex and #getMaxIndex define the boundaries available to #extract. DocumentExtractor objects *must* be closed when the results are no longer traversed. #close
