title: Passing an Object from LineCallbackHandler to ItemWriter
body: <p>I am writing a batch application which reads line-by-line from a file, process the content and write to database. Am using <code>FlatFileItemReader</code> for reading from file.</p>
  
  <p>The first line in the file is special (header) which is skipped using linesToSkip and processed using a <code>LineCallbackHandler</code> (<code>HeaderHandler</code>). The <code>HeaderHandler</code> builds a cache using the header information.</p>
  
  <p>Now I want to make use of this cache within my <code>ItemWriter</code>. Am not sure how to pass the cache object I build within <code>HeaderHandler</code> to my <code>ItemWriter</code>. Is there a clean way of doing this? </p>
