Field Summary
`static java.lang.String` | `CORE_DOCUMENT_REL`

Constructor Summary
`ExtractorFactory()`

Method Summary
`static org.apache.poi.POIOLE2TextExtractor` | `createExtractor(org.apache.poi.poifs.filesystem.DirectoryNode poifsDir, org.apache.poi.poifs.filesystem.POIFSFileSystem fs)`
`static org.apache.poi.POITextExtractor` | `createExtractor(java.io.File f)`
`static org.apache.poi.POITextExtractor` | `createExtractor(java.io.InputStream inp)`
`static POIXMLTextExtractor` | `createExtractor(OPCPackage pkg)`
`static org.apache.poi.POIOLE2TextExtractor` | `createExtractor(org.apache.poi.poifs.filesystem.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 org.apache.poi.POITextExtractor[]` | `getEmbededDocsTextExtractors(org.apache.poi.POIOLE2TextExtractor ext)` Returns an array of text extractors, one for each of the embeded documents in the file (if there are any).
`static org.apache.poi.POITextExtractor[]` | `getEmbededDocsTextExtractors(POIXMLTextExtractor ext)` Returns an array of text extractors, one for each of the embeded documents in the file (if there are any).
`static java.lang.Object` | `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(java.lang.Object preferEventExtractors)` Should this thread prefer event based over usermodel based extractors? Will only be used if the All Threads setting is null.
