detect()

virtual OUString SAL_CALL oox::core::FilterDetect::detect ( css::uno::Sequence< css::beans::PropertyValue > &  rMediaDescSeq )

overridevirtual

Detects MS Office 2007 file types and supports package decryption.

The following file types are detected:

• MS Word 2007 XML Document (*.docx, *.docm)
• MS Word 2007 XML Template (*.dotx, *.dotm)
• MS Excel 2007 XML Document (*.xlsx, *.xlsm)
• MS Excel 2007 BIFF12 Document (*.xlsb)
• MS Excel 2007 XML Template (*.xltx, *.xltm)
• MS Powerpoint 2007 XML Document (*.pptx, *.pptm)
• MS Powerpoint 2007 XML Template (*.potx, *.potm)

If the package is encrypted, the detection tries to decrypt it into a temporary file. The user may be asked for a password. The XStream interface of the temporary file will be stored in the 'ComponentData' property of the passed media descriptor.

extractUnencryptedPackage()

Reference< XInputStream > FilterDetect::extractUnencryptedPackage

(

utl::MediaDescriptor &

rMediaDesc

)

const

Tries to extract an unencrypted ZIP package from the passed media descriptor.

First, this function checks if the input stream provided by the media descriptor property 'InputStream' contains a ZIP package. If yes, this stream is returned.

Second, this function checks if the 'ComponentData' property exists and contains a sequence of com.sun.star.beans.NamedValue. If yes, a named value is searched with the name 'DecryptedPackage' and a value of type com.sun.star.io.XStream. If the input stream provided by this XStream contains a ZIP package, this input stream is returned.

Third, this function checks if the input stream of the media descriptor contains an OLE package. If yes, it checks the existence of the streams 'EncryptionInfo' and 'EncryptedPackage' and tries to decrypt the package into a temporary file. This may include requesting a password from the media descriptor property 'Password' or from the user, using the interaction handler provided by the descriptor. On success, and if the decrypted package is a ZIP package, the XStream of the temporary file is stored in the property 'ComponentData' of the media descriptor and its input stream is returned.
