Method Detail

setListeners

public void setListeners(RepeatListener[] listeners)

Public setter for the listeners.

Parameters:

listeners -

register

public void register(RepeatListener listener)

Register additional listener.

Parameters:

listener -

after

public void after(RepeatContext context,
         RepeatStatus 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

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.

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
