Interface IContentProcessor is invoked by Windchill services before the content is stored. The content that is uploaded to Windchill server is passed on to this interface in the form of InputStream and map. This map contains information about the vault file path, the vault file name, and the operation name (Upload/Copy). After scanning the content for virus, InputStream and the file length is returned via ProcessResult. You can customize the interface to display WTException with appropriate message if virus is found during the scan or if the interface is not able to communicate with the antivirus software. The message in WTException will be displayed as a user interface alert.
