static POIXMLTextExtractor	createExtractor(OPCPackage pkg)
static POIOLE2TextExtractor	createExtractor(POIFSFileSystem fs)
static java.lang.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 POITextExtractor[]	getEmbededDocsTextExtractors(POIOLE2TextExtractor ext) Returns an array of text extractors, one for each of the embeded documents in the file (if there are any).
static POITextExtractor[]	getEmbededDocsTextExtractors(POIXMLTextExtractor ext) Returns an array of text extractors, one for each of the embeded documents in the file (if there are any).
protected 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(java.lang.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.
