#31 Allow cell processors to be used with variable no of columns

[James Bassett]

Some CSV files don't conform to RFC4180 and have a different number of columns on each row. Currently, that limits people to using CsvListReader without any processors (returned as a List of Strings).

This issue has been reported on StackOverflow as well has on the forums (here and here). It's also related to this other feature request.

Update CsvListReader to allow the execution of cell processors after a row is read.

Implemented by [r281]

You can now execute the cell processors after reading a line! (only applicable to CsvListReader)

while( (listReader.read()) != null ) {

  // use different processors depending on the number of columns
  final CellProcessor[] processors;
  if( listReader.length() == noBirthDateProcessors.length ) {
    processors = noBirthDateProcessors;
  } else {
    processors = allProcessors;
  }

  final List<Object> customerList = 
    listReader.executeProcessors(processors);

}
