Interface DeferredTask

• All Superinterfaces:

  java.lang.Runnable, java.io.Serializable

  ---

  
  

  public interface DeferredTask
  extends java.lang.Runnable, java.io.Serializable

  Interface for deferred tasks. Classes implementing this interface may use TaskOptions.payload(DeferredTask) to serialize the DeferredTask into the payload of the task definition. The Runnable.run() method will be called when the task is received by the built in DeferredTask servlet.

  Normal return from this method is considered success and will not retry unless DeferredTaskContext.markForRetry() is called. Exceptions thrown from this method will indicate a failure and will be processed as a retry attempt unless DeferredTaskContext.setDoNotRetry(boolean) was set to true.
