Examples of org.springframework.batch.item.ExecutionContext

org.springframework.batch.item.ExecutionContext
Object representing a context for an {@link ItemStream}. It is a thin wrapper for a map that allows optionally for type safety on reads. It also allows for dirty checking by setting a 'dirty' flag whenever any put is called. Note that putting null value is equivalent to removing the entry for the given key. @author Lucas Ward @author Douglas Kaminsky
