Description copied from interface: ItemProcessor

Process the provided item, returning a potentially modified or new item for continued processing. If the returned result is null, it is assumed that processing of the item should not continue. A null item will never reach this method because the only possible sources are:

• an ItemReader (which indicates no more items)
• a previous ItemProcessor in a composite processor (which indicates a filtered item)

Specified by:

process in interface ItemProcessor<I,O>

Parameters:

item - to be processed, never null.

Returns:

potentially modified or new item for continued processing, null if processing of the provided item should not continue.

Throws:

java.lang.Exception - thrown if exception occurs during processing.
