Package org.apache.tika.detect.siegfried

Class SiegfriedDetector

java.lang.Object

org.apache.tika.detect.siegfried.SiegfriedDetector

All Implemented Interfaces:

Serializable, org.apache.tika.detect.Detector

public class SiegfriedDetector
extends Object
implements org.apache.tika.detect.Detector

Simple wrapper around Siegfried https://github.com/richardlehane/siegfried The default behavior is to run detection, report the results in the metadata and then return null so that other detectors will be used.

Method Details

checkHasSiegfried

public static boolean checkHasSiegfried(String siegfriedCommandPath)

detect

public org.apache.tika.mime.MediaType detect(InputStream input,
 org.apache.tika.metadata.Metadata metadata)
                                      throws IOException

Specified by:

detect in interface org.apache.tika.detect.Detector

Parameters:

input - document input stream, or null

metadata - input metadata for the document

Returns:

mime as identified by the file command or application/octet-stream otherwise

Throws:

IOException

setUseMime

@Field
public void setUseMime(boolean useMime)

As default behavior, Tika runs Siegfried to add its detection to the metadata, but NOT to use detection in determining parsers etc. If this is set to true, this detector will return the first mime detected by Siegfried and that mime will be used by the AutoDetectParser to select the appropriate parser.

Parameters:

useMime -

isUseMime

public boolean isUseMime()

processResult

protected static org.apache.tika.mime.MediaType processResult(org.apache.tika.utils.FileProcessResult result,
 org.apache.tika.metadata.Metadata metadata,
 boolean returnMime)

setSiegfriedPath

@Field
public void setSiegfriedPath(String fileCommandPath)

setMaxBytes

@Field
public void setMaxBytes(int maxBytes)

If this is not called on a TikaInputStream, this detector will spool up to this many bytes to a file to be detected by the 'file' command.

Parameters:

maxBytes -

setTimeoutMs

@Field
public void setTimeoutMs(long timeoutMs)
