ElectStateFilter (Carrot Task Queue 2.0.2 API)

All Superinterfaces:

TaskFilter

All Known Implementing Classes:

RetryFilter
```
public interface ElectStateFilter
extends TaskFilter
```
A filter that is triggered each time that the state of a Task is changed (except when the Task is deleted via the Dashboard). This filter will be called before that the task has been saved to a PartitionedStorageProvider. Altering the task will change the lifecycle of the task - an example of this is the RetryFilter which updates tasks that are failed to scheduled again. Every ElectStateFilter must also respect the allowed state changes. See AllowedTaskStateStateChanges for more info.
