Method Details

detect

@Deprecated
protected static MediaType detect(Set<String> names)

Deprecated.

Use detect(Set, DirectoryEntry) and pass the root entry of the filesystem whose type is to be detected, as a second argument.

Internal detection of the specific kind of OLE2 document, based on the names of the top level streams within the file.

detect

protected static MediaType detect(Set<String> names,
 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.

Parameters:

names -

root -

Returns:

detect

public MediaType detect(TikaInputStream tis,
 Metadata metadata,
 ParseContext parseContext)
                 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 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:

tis - document input stream, or null

metadata - input metadata for the document

parseContext - the parse context

Returns:

detected media type, or application/octet-stream

Throws:

IOException - if the document input stream could not be read
