Interface ZipContainerDetector

All Superinterfaces:

Serializable

All Known Implementing Classes:

IPADetector, IWorkDetector, JarDetector, KMZDetector, OPCPackageDetector, 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
MediaType	detect(org.apache.commons.compress.archivers.zip.ZipFile zipFile, TikaInputStream tis) If detection is successful, the ZipDetector should set the zip file or OPCPackage in TikaInputStream.setOpenContainer() Implementations should _not_ close the ZipFile
MediaType	streamingDetectFinal(StreamingDetectContext detectContext) After we've finished streaming the zip archive entries, a detector may make a final decision.
MediaType	streamingDetectUpdate(org.apache.commons.compress.archivers.zip.ZipArchiveEntry zae, InputStream zis, StreamingDetectContext detectContext) Try to detect on a specific entry.

Method Detail

detect

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

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

Parameters:

zipFile -

tis -

Returns:

Throws:

IOException

streamingDetectUpdate

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

MediaType streamingDetectFinal(StreamingDetectContext detectContext)

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

Returns:
