RepeatListenerSupport

public RepeatListenerSupport()
Method Detail

before

public void before(RepeatContext context)
Description copied from interface: RepeatListener
Called by the framework before each batch item. Implementers can halt a batch by setting the complete flag on the context.

Specified by:
before in interface RepeatListener
Parameters:
context - the current batch context.

after

public void after(RepeatContext context,
                  ExitStatus result)
Description copied from interface: RepeatListener
Called by the framework after each item has been processed, unless the item processing results in an exception. This method is called as soon as the result is known.

Specified by:
after in interface RepeatListener
Parameters:
context - the current batch context
result - the result of the callback

close

public void close(RepeatContext context)
Description copied from interface: RepeatListener
Called once at the end of a complete batch, after normal or abnormal completion (i.e. even after an exception). Implementers can use this method to clean up any resources.

Specified by:
close in interface RepeatListener
Parameters:
context - the current batch context.

onError

public void onError(RepeatContext context,
                    Throwable e)
Description copied from interface: RepeatListener
Called when a repeat callback fails by throwing an exception. There will be one call to this method for each exception thrown during a repeat operation (e.g. a chunk).
There is no need to re-throw the exception here - that will be done by the enclosing framework.

Specified by:
onError in interface RepeatListener
Parameters:
context - the current batch context
e - the error that was encountered in an item callback.

open

public void open(RepeatContext context)
Description copied from interface: RepeatListener
Called once at the start of a complete batch, before any items are processed. Implementers can use this method to acquire any resources that might be needed during processing. Implementers can halt the current operation by setting the complete flag on the context. To halt all enclosing batches (the whole job), the would need to use the parent context (recursively).

Specified by:
open in interface RepeatListener
Parameters:
context - the current batch context
