Class ExtractionResultImpl

java.lang.Object

org.apache.any23.extractor.ExtractionResultImpl

All Implemented Interfaces:

ExtractionResult, IssueReport, TagSoupExtractionResult

public class ExtractionResultImpl
extends Object
implements TagSoupExtractionResult

A default implementation of ExtractionResult; it receives extraction output from one Extractor working on one document, and passes the output on to a TripleHandler. It deals with details such as creation of ExtractionContext objects and closing any open contexts at the end of extraction.

The close() method must be invoked after the extractor has finished processing.

There is usually no need to provide additional implementations of the ExtractionWriter interface.
