<p><code class="classname">ItemProcessor</code> is an abstraction that
|
||
represents the business processing of an item. While the
|
||
<code class="classname">ItemReader</code> reads one item, and the
|
||
<code class="classname">ItemWriter</code> writes them, the
|
||
<code class="classname">ItemProcessor</code> provides access to transform or apply
|
||
other business processing. If, while processing the item, it is determined
|
||
that the item is not valid, returning null indicates that the item should
|
||
not be written out. More details about the ItemProcessor interface can be
|
||
found in <a class="xref" href="ch06.xhtml" title="Chapter 6. ItemReaders and ItemWriters">Chapter 6, <em>ItemReaders and ItemWriters</em></a>.</p>
