/**
 * Cancels the check out of the file entry. If a user has not checked out
 * the specified file entry, invoking this method will result in no changes.
 *
 * <p>//from  w w w .  j a  va 2s .  co  m
 * When a file entry is checked out, a PWC (private working copy) is created
 * and the original file entry is locked. A client can make as many changes
 * to the PWC as he desires without those changes being visible to other
 * users. If the user is satisfied with the changes, he may elect to check
 * in his changes, resulting in a new file version based on the PWC; the PWC
 * will be removed and the file entry will be unlocked. If the user is not
 * satisfied with the changes, he may elect to cancel his check out; this
 * results in the deletion of the PWC and unlocking of the file entry.
 * </p>
 *
