Interface DocumentExtractor

All Known Implementing Classes:

DocumentExtractorImpl

public interface 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(int). DocumentExtractor objects *must* be closed when the results are no longer traversed. See close()
