- - org.ow2.proactive.scheduler.common.task.Task
  - - org.ow2.proactive.scheduler.common.task.TaskState

All Implemented Interfaces:

Serializable, Comparable<TaskState>

Direct Known Subclasses:

ClientTaskState, TaskStateImpl, TaskStateImpl
```
@PublicAPI
public abstract class TaskState
extends Task
implements Comparable<TaskState>
```
This class contains all informations about the state of the task. It also provides methods and static fields to order the tasks if you hold them in a list.
