org.apache.tika.detect.zip

Interface ZipContainerDetector

All Superinterfaces:

Serializable

All Known Implementing Classes:

IPADetector, JarDetector, KMZDetector, OpenDocumentDetector, StarOfficeDetector

public interface ZipContainerDetector
extends Serializable

Classes that implement this must be able to detect on a ZipFile and in streaming mode. In streaming mode, each ziparchiventry is "updated" and then streamingDetectFinal(StreamingDetectContext) is called for a final decision.

During streaming detection, state is stored in the StreamingDetectContext

Method Summary

Modifier and Type	Method and Description
org.apache.tika.mime.MediaType	detect(org.apache.commons.compress.archivers.zip.ZipFile zipFile, org.apache.tika.io.TikaInputStream tis) If detection is successful, the ZipDetector should set the zip file or OPCPackage in TikaInputStream.setOpenContainer()
org.apache.tika.mime.MediaType	streamingDetectFinal(StreamingDetectContext detectContext) After we've finished streaming the zip archive entries, a detector may make a final decision.
org.apache.tika.mime.MediaType	streamingDetectUpdate(org.apache.commons.compress.archivers.zip.ZipArchiveEntry zae, InputStream zis, StreamingDetectContext detectContext) Try to detect on a specific entry.

Method Detail

detect

org.apache.tika.mime.MediaType detect(org.apache.commons.compress.archivers.zip.ZipFile zipFile,
                                      org.apache.tika.io.TikaInputStream tis)
                               throws IOException

If detection is successful, the ZipDetector should set the zip file or OPCPackage in TikaInputStream.setOpenContainer()

Parameters:

zipFile -

tis -

Returns:

Throws:

IOException

streamingDetectUpdate

org.apache.tika.mime.MediaType streamingDetectUpdate(org.apache.commons.compress.archivers.zip.ZipArchiveEntry zae,
                                                     InputStream zis,
                                                     StreamingDetectContext detectContext)
                                              throws IOException

Try to detect on a specific entry. Detectors are allowed to store state (e.g. "remember what they've seen") in the StreamingDetectContext

Parameters:

zae -

Returns:

Throws:

IOException

streamingDetectFinal

org.apache.tika.mime.MediaType streamingDetectFinal(StreamingDetectContext detectContext)

After we've finished streaming the zip archive entries, a detector may make a final decision.

Returns:
