- org.apache.tika.detect.microsoft.POIFSContainerDetector

All Implemented Interfaces:

Serializable, Detector
```
public class POIFSContainerDetector
extends Object
implements Detector
```
A detector that works on a POIFS OLE2 document to figure out exactly what the file is. This should work for all OLE2 documents, whether they are ones supported by POI or not.

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`MediaType`	`detect(InputStream input, Metadata metadata)`	Detects the content type of the given input document.
`static MediaType`	`detect(Set<String> anyCaseNames, org.apache.poi.poifs.filesystem.DirectoryEntry root)`	Internal detection of the specific kind of OLE2 document, based on the names of the top-level streams within the file.
`void`	`setMarkLimit(int markLimit)`	If a TikaInputStream is passed in to `detect(InputStream, Metadata)`, and there is not an underlying file, this detector will spool up to `markLimit` to disk.

public static MediaType detect(Set<String> anyCaseNames,
                               org.apache.poi.poifs.filesystem.DirectoryEntry root)
```
    Internal detection of the specific kind of OLE2 document, based on the names of the top-level streams within the file. In some cases the detection may need access to the root DirectoryEntry of that file for best results. The entry can be given as a second, optional argument.
    Following 2.6.1 of MS-CFB , The detection is performed on case insensitive entry names.
    
    Parameters:
    
    anyCaseNames -
    
    root -
    
    Returns:
  - setMarkLimit
```
public void setMarkLimit(int markLimit)
```
    If a TikaInputStream is passed in to detect(InputStream, Metadata), and there is not an underlying file, this detector will spool up to markLimit to disk. If the stream was read in entirety (e.g. the spooled file is not truncated), this detector will open the file with POI and perform detection. If the spooled file is truncated, the detector will return OLE (or MediaType.OCTET_STREAM if there's no OLE header).
    As of Tika 1.21, this detector respects the legacy behavior of not performing detection on a non-TikaInputStream.
    
    Parameters:
    
    markLimit -
  - detect
```
public MediaType detect(InputStream input,
                        Metadata metadata)
                 throws IOException
```
    Description copied from interface: Detector
    
    Detects the content type of the given input document. Returns application/octet-stream if the type of the document can not be detected.
    If the document input stream is not available, then the first argument may be null. Otherwise the detector may read bytes from the start of the stream to help in type detection. The given stream is guaranteed to support the mark feature and the detector is expected to mark the stream before reading any bytes from it, and to reset the stream before returning. The stream must not be closed by the detector.
    The given input metadata is only read, not modified, by the detector.
    
    Specified by:
    
    detect in interface Detector
    
    Parameters:
    
    input - document input stream, or null
    
    metadata - input metadata for the document
    
    Returns:
    
    detected media type, or application/octet-stream
    
    Throws:
    
    IOException - if the document input stream could not be read
  - tryOpenContainerOnTikaInputStream
```
public static Set<String> tryOpenContainerOnTikaInputStream(InputStream input,
                                                            Metadata metadata)
