Class RetryableTask

java.lang.Object
  com.samskivert.swing.util.RetryableTask

public abstract class RetryableTask
extends Object

A retryable task is one that is allowed to fail at which point a dialog is presented to the user asking them if they would like to retry the task. In general, such practices are discouraged because the software should handle retrying itself, but in cases where failure results in the abandonment of a lot of work and automatic retries have already been tried, it can be reasonable to give the user one last chance to remedy any problems that are causing the error.
