Interface LabelAssignmentAction

All Superinterfaces:

Action, ModelObject

All Known Implementing Classes:

ParametersAction

public interface LabelAssignmentAction
extends Action

Action that can be submitted to Queue that controls where the task runs.

Where to insert LabelAssignmentActions

If you control when the task gets submitted to the queue, you can associate this action to the task by passing it as a parameter to method like Queue.schedule(Task, int, Action...).

If you want to globally affect the scheduling decision, you can do so by Queue.QueueDecisionHandler and alter the list of actions that you get. Alternatively, you can implement your own LoadBalancer and bypass the whole label/assignment mechanism to control the decision into your own hands.
