Class PollingTaskController.PollingCancelingState

java.lang.Object
  edu.rice.cs.plt.concurrent.TaskController.State

Enclosing class:

PollingTaskController<R>

protected class PollingTaskController.PollingCancelingState
extends TaskController.CancelingState

CancelingState variant based on a PollingRunner. Extends Canceling to allow it to be recognized as that type. (A lot of code is duplicated from PollingRunningState, but that seems inevitable without overhauling the design to use interfaces to identify different kinds of states.)
