  org.apache.tika.parser.microsoft.ooxml.AbstractOOXMLExtractor

All Implemented Interfaces:

OOXMLExtractor

Direct Known Subclasses:

POIXMLTextExtractorDecorator, XSLFPowerPointExtractorDecorator, XSSFExcelExtractorDecorator, XWPFWordExtractorDecorator

public abstract class AbstractOOXMLExtractor
extends Object
implements OOXMLExtractor

Base class for all Tika OOXML extractors. Tika extractors decorate POI extractors so that the parsed content of documents is returned as a sequence of XHTML SAX events. Subclasses must implement the buildXHTML method buildXHTML(XHTMLContentHandler) that populates the XHTMLContentHandler object received as parameter.
