Class TaskState

java.lang.Object

com.sapportals.wcm.util.enums.AbstractEnum

com.sapportals.wcm.service.taskqueue.TaskState

All Implemented Interfaces:

Serializable

public class TaskState
extends AbstractEnum

This class defines the identifiers for the different lifecycle states of a task in the task queue service.

If a new task is added to the task queue the task's state will be set to NEW. If a task is fetched from the queue it's state will be set to ACTIVE to indicate that the task is currently being processed. The processor itself should set the task's state to DONE ifthe task was processed sucessfully or ERROR if the task failed.

If an active task is added to ther queue an exception will be raised. It is possible to add tasks that are done (have the DONE-state) to run them once again.
