Method Details

process

protected IteratingCallback.Action process()
                                    throws Exception

Description copied from class: IteratingCallback

Method called by IteratingCallback.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 yet
• IteratingCallback.Action.SCHEDULED when the sub task asynchronous execution has been started
• IteratingCallback.Action.SUCCEEDED when the overall job is completed

Specified by:

process in class IteratingCallback

Returns:

the appropriate Action

Throws:

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 interface Callback

Overrides:

succeeded in class IteratingCallback

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 class IteratingCallback

See Also:

• IteratingCallback.onCompleteFailure(Throwable)

onCompleteFailure

protected void onCompleteFailure(Throwable failure)

Description copied from class: IteratingCallback

Invoked when the overall task has completed with a failure.

Overrides:

onCompleteFailure in class IteratingCallback

Parameters:

failure - the throwable to indicate cause of failure

See Also:

• IteratingCallback.onCompleteSuccess()

getInvocationType

public Invocable.InvocationType getInvocationType()

Specified by:

getInvocationType in interface Invocable

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 interface AsyncContentProvider.Listener
