Allow custom unmarshalling of xml fragments in StaxEventItemReader [BATCH-2357]

[spring-projects-issues]

Krishna Bhamidipati opened BATCH-2357 and commented

Currently, the reader allows for some custom logic in the doRead method via the protected moveCursorToNextFragment method.

It would be convenient to plug-in custom logic for mapping the fragment as well by refactoring the doRead method to call another protected method like below:

protected T mapFragment(FragmentEventReader fragmentReader) {
    T mappedFragment = (T) unmarshaller.unmarshal(StaxUtils.getSource(fragmentReader));
    return mappedFragment;
}

I agree on the idea of extracting a method for the mapping part, but what would the custom mapping code be other than unmarshaller.unmarshal(StaxUtils.getSource(fragmentReader)) ? Can you give a use case with a code example?
