/**
 * Updates a file entry and associated metadata based on an {@link
 * InputStream} object. If the file data is <code>null</code>, then only the
 * associated metadata (i.e., <code>title</code>, <code>description</code>,
 * and parameters in the <code>serviceContext</code>) will be updated.
 *
 * <p>//  w w  w.  j av  a 2  s  .  c om
 * This method takes two file names, the <code>sourceFileName</code> and the
 * <code>title</code>. The <code>sourceFileName</code> corresponds to the
 * name of the actual file being uploaded. The <code>title</code>
 * corresponds to a name the client wishes to assign this file after it has
 * been uploaded to the portal.

 *
 * @param  userId the primary key of the user
 * @param  fileEntryId the primary key of the file entry
 * @param  sourceFileName the original file's name (optionally
 *         <code>null</code>)
 * @param  mimeType the file's MIME type (optionally <code>null</code>)
 * @param  title the new name to be assigned to the file (optionally <code>
 *         <code>null</code></code>)
 * @param  description the file's new description
 * @param  changeLog the file's version change log (optionally

 * @param  is the file's data (optionally <code>null</code>)
 * @param  size the file's size (optionally <code>0</code>)
 * @param  serviceContext the service context to be applied. Can set the
 *         asset category IDs, asset tag names, and expando bridge
 *         attributes for the file entry. In a Liferay repository, it may
