Method Detail

getTotalProgress

public double getTotalProgress()

The total value that this progress represents. This should be specific to your task, not in terms of percent complete, as the percentage values will be calculated automatically by the ProgressBar.

Specified by:

getTotalProgress in interface ProgressWorker

Returns:

Number representing the total value for this progress bar.

getCurrentProgress

public double getCurrentProgress()

Should represent a number value indicating the current progress value out of the total derived in ProgressWorker.getTotalProgress().

Specified by:

getCurrentProgress in interface ProgressWorker

Returns:

The current progress value.

getCurrentStatus

public String getCurrentStatus()

If value not null will be used to display any textual information that may be useful to see along with the basic numeric values.

Specified by:

getCurrentStatus in interface ProgressWorker

Returns:

String representation of what is currently being worked on by this task.

isComplete

public boolean isComplete()

Should return true once the task is completed.

Specified by:

isComplete in interface ProgressWorker

Returns:

True, if and only if the thread represented by this task is complete.

cancelTask

public void cancelTask()

Can be invoked by a user inpatient to see the request completed. Method doesn't have to cancel exactly when called, or at all, but it is expected that this method will block at least until the task is complete. Only return from this call if calling ProgressWorker.isComplete() will return true.

Specified by:

cancelTask in interface ProgressWorker

run

public void run()

Specified by:

run in interface Runnable

Overrides:

run in class Thread
