Class WorkerTask

java.lang.Object
com.gargoylesoftware.base.gui.WorkerTask

public abstract class WorkerTask extends Object
A task that partially executes on a non-ui thread and partially on the ui thread.

It is common to have tasks that have a non-ui portion followed by a ui portion. For example, a database query must take place on a non-ui thread because is it a blocking call. The code that takes the results of that query must execute on the UI thread if it is to update UI components.

This task will be called in the following way. First, the method runOnWorkerThread() will be called from a non-UI thread. At some point later (usually almost immediately), the method runOnUIThread() will be called from the UI thread.
