Class POIXMLExtractorFactory

java.lang.Object

org.apache.poi.ooxml.extractor.POIXMLExtractorFactory

All Implemented Interfaces:

ExtractorProvider

public final class POIXMLExtractorFactory
extends Object
implements ExtractorProvider

Figures out the correct POITextExtractor for your supplied document, and returns it.

Note 1 - will fail for many file formats if the POI Scratchpad jar is not present on the runtime classpath

Note 2 - rather than using this, for most cases you would be better off switching to Apache Tika instead!

boolean	accepts(FileMagic fm)
POITextExtractor	create(DirectoryNode poifsDir, String password)
POITextExtractor	create(File f, String password)
POITextExtractor	create(InputStream inp, String password)
POIXMLTextExtractor	create(OPCPackage pkg) Tries to determine the actual type of file and produces a matching text-extractor for it.
POITextExtractor	create(POIFSFileSystem fs)
static Boolean	getAllThreadsPreferEventExtractors() Should all threads prefer event based over usermodel based extractors? (usermodel extractors tend to be more accurate, but use more memory) Default is to use the thread level setting, which defaults to false.
static boolean	getPreferEventExtractor() Should this thread use event based extractors is available? Checks the all-threads one first, then thread specific.
static boolean	getThreadPrefersEventExtractors() Should this thread prefer event based over usermodel based extractors? (usermodel extractors tend to be more accurate, but use more memory) Default is false.
static void	setAllThreadsPreferEventExtractors(Boolean preferEventExtractors) Should all threads prefer event based over usermodel based extractors? If set, will take preference over the Thread level setting.
static void	setThreadPrefersEventExtractors(boolean preferEventExtractors) Should this thread prefer event based over usermodel based extractors? Will only be used if the All Threads setting is null.
