 * An entity class that wraps converted data, conversion status, and the

 * An instance of this class may be created two ways by the drm framework:
 * a) a call to {@link DrmManagerClient#convertData DrmManagerClient.convertData()} and
 * b) a call to {@link DrmManagerClient#closeConvertSession DrmManagerClient.closeConvertSession()}.
 * An valid offset value is provided only from a success call to
 * {@link DrmManagerClient#closeConvertSession DrmManagerClient.closeConvertSession()}.

 * @deprecated Please use {@link android.media.MediaDrm}
