Method Detail

• read

  public Order read()
             throws java.lang.Exception

  Description copied from interface: ItemReader
  Reads a piece of input data and advance to the next one. Implementations must return null at the end of the input data set. In a transactional setting, caller might get the same item twice from successive calls (or otherwise), if the first call was in a transaction that rolled back.

  Specified by:

  read in interface ItemReader<Order>

  Returns:

  T the item to be processed or null if the data source is exhausted

  Throws:

  ParseException - if there is a problem parsing the current record (but the next one may still be valid)

  NonTransientResourceException - if there is a fatal exception in the underlying resource. After throwing this exception implementations should endeavour to return null from subsequent calls to read.

  UnexpectedInputException - if there is an uncategorised problem with the input data. Assume potentially transient, so subsequent calls to read might succeed.

  java.lang.Exception - if an there is a non-specific error.
