code: void addData(String tag, long timestamp, byte[] data) {
      entries.put(timestamp, new DropBoxManager.Entry(tag, timestamp, data, DropBoxManager.IS_TEXT));
    }
docs: Adds entry to the DropboxManager with the flag indicating data is text.
  
  <p>The existing {@link DropBoxManager#addData}, {@link DropBoxManager#addFile}, and {@link
  DropBoxManager#addText} methods in DropBoxManager are not shadowed. This method is a
  convenience for quickly adding multiple historical entries. The entries can be added in any
  order since this shadow will sort the entries by the specified timestamp.
  
  <p>The flag will be set to {@link DropBoxManager#IS_TEXT} so that {@link
  DropBoxManager.Entry#getText} can be used.
  
  @param tag can be any arbitrary string
  @param timestamp is an arbitrary timestamp that must be unique from all other entries
  @param data must not be null
