process
protected IteratingCallback.Action process() throws java.lang.Exception
Description copied from class:IteratingCallback
Method called byIteratingCallback.iterate()
to process the asynchronous sub-task.Implementations must initiate the asynchronous execution of the sub-task (if any) and return an appropriate action:
IteratingCallback.Action.IDLE
when no sub tasks are available for execution but the overall job is not completed yetIteratingCallback.Action.SCHEDULED
when the sub task asynchronous execution has been startedIteratingCallback.Action.SUCCEEDED
when the overall job is completed
- Specified by:
process
in classIteratingCallback
- Returns:
- the appropriate Action
- Throws:
java.lang.Exception
-
succeeded
public void succeeded()
Description copied from class:IteratingCallback
Method to invoke when the asynchronous sub-task succeeds.Subclasses that override this method must always remember to call
super.succeeded()
.- Specified by:
succeeded
in interfaceCallback
- Overrides:
succeeded
in classIteratingCallback
- See Also:
Callback.failed(Throwable)
-
onCompleteSuccess
protected void onCompleteSuccess()
Description copied from class:IteratingCallback
Invoked when the overall task has completed successfully.- Overrides:
onCompleteSuccess
in classIteratingCallback
- See Also:
IteratingCallback.onCompleteFailure(Throwable)
-
onCompleteFailure
protected void onCompleteFailure(java.lang.Throwable failure)
Description copied from class:IteratingCallback
Invoked when the overall task has completed with a failure.- Overrides:
onCompleteFailure
in classIteratingCallback
- Parameters:
failure
- the throwable to indicate cause of failure- See Also:
IteratingCallback.onCompleteSuccess()
-
getInvocationType
public Invocable.InvocationType getInvocationType()
- Specified by:
getInvocationType
in interfaceInvocable
- Returns:
- The InvocationType of this object
-
onContent
public void onContent()
Description copied from interface:AsyncContentProvider.Listener
Callback method invoked when content is available- Specified by:
onContent
in interfaceAsyncContentProvider.Listener
