+     * Initializes the transfer with certain properties.  This function must

+     *
+     * @param aSource The source URI of the transfer. Must not be null.
+     *
+     * @param aTarget The target URI of the transfer. Must not be null.
+     *
+     * @param aDisplayName The user-readable description of the transfer.
+     *                     Can be empty.
+     *
+     * @param aMIMEInfo The MIME info associated with the target,
+     *                  including MIME type and helper app when appropriate.
+     *                  This parameter is optional.
+     *
+     * @param startTime Time when the download started (ie, when the first
+     *                  response from the server was received)
+     *                  XXX presumably wbp and exthandler do this differently
+     *
+     * @param aTempFile The location of a temporary file; i.e. a file in which
+     *                  the received data will be stored, but which is not
+     *                  equal to the target file. (will be moved to the real
+     *                  target by the caller, when the download is finished)
+     *                  May be null.
+     *
+     * @param aCancelable An object that can be used to abort the download.
+     *                    Must not be null.
+     *                    Implementations are expected to hold a strong
+     *                    reference to this object until the download is
+     *                    finished, at which point they should release the
+     *                    reference.
+     *
+     * @param aIsPrivate Used to determine the privacy status of the new transfer.
+     *                   If true, indicates that the transfer was initiated from
+     *                   a source that desires privacy.
