Constructor Details
- NewsFetcher
  
  public NewsFetcher(RouterContext ctx, ConsoleUpdateManager mgr, List<URI> uris)
Method Details
- run
  
  public void run()
  
  Specified by:
  
  run in interface Runnable
  
  Overrides:
  
  run in class UpdateRunner
- fetchNews
  
  public void fetchNews()
- checkForUpdates
  
  void checkForUpdates()
  
  Parse the installed (not the temp) news file for the latest version. TODO: Real XML parsing TODO: Check minVersion, use backup URLs specified TODO: SU3
- bytesTransferred
  
  public void bytesTransferred(long alreadyTransferred, int currentWrite, long bytesTransferred, long bytesRemaining, String url)
  
  override to prevent status update
  
  Specified by:
  
  bytesTransferred in interface EepGet.StatusListener
  
  Overrides:
  
  bytesTransferred in class UpdateRunner
  
  Parameters:
  
  alreadyTransferred - total of all attempts, not including currentWrite If nonzero on the first call, a partial file of that length was found, _and_ the server supports resume. If zero on a subsequent call after some bytes are transferred (and presumably after an attemptFailed), the server does _not_ support resume and we had to start over. To track _actual_ transfer if the output file could already exist, the listener should keep its own counter, or subtract the initial alreadyTransferred value. And watch out for alreadyTransferred resetting if a resume failed...
  
  currentWrite - since last call to the listener
  
  bytesTransferred - includes headers, retries, redirects, discarded partial downloads, ...
  
  bytesRemaining - on this attempt only, currentWrite already subtracted - or -1 if chunked encoding or server does not return a length
- headerReceived
  
  public void headerReceived(String url, int attemptNum, String key, String val)
  
  Overriden to get the last-modified header
  
  Specified by:
  
  headerReceived in interface EepGet.StatusListener
  
  Overrides:
  
  headerReceived in class UpdateRunner
- transferComplete
  
  public void transferComplete(long alreadyTransferred, long bytesTransferred, long bytesRemaining, String url, String outputFile, boolean notModified)
  
  Copies the file from temp dir to the news location, calls checkForUpdates()
  
  Specified by:
  
  transferComplete in interface EepGet.StatusListener
  
  Overrides:
  
  transferComplete in class UpdateRunner
  
  outputFile - null if unknown (output stream constructor)
  
  See Also:
  
  EepGet.StatusListener.bytesTransferred(long, int, long, long, java.lang.String)
- transferFailed
  
  public void transferFailed(String url, long bytesTransferred, long bytesRemaining, int currentAttempt)
  
  override to prevent status update
  
  Specified by:
  
  transferFailed in interface EepGet.StatusListener
  
  Overrides:
  
  transferFailed in class UpdateRunner
