    protected boolean _isRunning

### done

    protected boolean done

### _get

    protected EepGet _get

### _pct

    protected final DecimalFormat _pct

Constructor Detail

### UpdateHandler.UpdateRunner

    public UpdateHandler.UpdateRunner()

Method Detail

### isRunning

    public boolean isRunning()

### isDone

    public boolean isDone()

### run

    public void run()

  Specified by:
    `run` in interface `Runnable`

### update

    protected void update()

  Loop through the entire list of update URLs. For each one, first get the version from the first 56 bytes and see if it is newer than what we are running now. If it is, get the whole thing.

### attemptFailed

    public void attemptFailed(String url,
                              long bytesTransferred,
                              long bytesRemaining,
                              int currentAttempt,
                              int numRetries,
                              Exception cause)

  Specified by:
    `attemptFailed` in interface `EepGet.StatusListener`

### bytesTransferred

    public void bytesTransferred(long alreadyTransferred,
                                 int currentWrite,
                                 long bytesTransferred,
                                 long bytesRemaining,
                                 String url)

  Description copied from interface: `EepGet.StatusListener`
  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 Total length should be == alreadyTransferred + currentWrite + bytesRemaining for all calls

    public void transferComplete(long alreadyTransferred,
                                 long bytesTransferred,
