Detailed Description

Manages access to a single item of drm protected content. Creating an instance of ContentLicence for a drm protected file allows that file to be accessed using the Qt file access API for the lifetime of the ContentLicence. When rendering protected content the ContentLicence should be updated with the usage infomation by calling renderStateChanged, and terminate rendering if the rightsExpired signal is emitted. When access to the file is no longer required release should be called to prevent further file access calls being allowed and to schedule the ContentLicence for deletion.

Applications should not use a ContentLicence directly, instead access should be requested using an instance of QDrmContent.
