TaskObserver (Cytoscape Swing App API (swing-app-api) 3.8.1 API)

Type Parameters:

R - The type of the result this observer is expected to receive.
```
public interface TaskObserver
```
An observer that gets notified when an ObservableTask finishes executing. If the task finishes, taskFinished() is called with whatever result the task produces, if any. When a task iterator finishes, the task manager will invoke allFinished with the appropriate FinishStatus object depending on the scenario in which the task iterator finished.
Module: work-api
To use this in your app, include the following dependency in your POM:
```
<dependency>
    <groupId>org.cytoscape</groupId>
    <artifactId>work-api</artifactId>
</dependency>
