New Methods in DataCell Derived Classes
We defined three derived classes to support CSV formats in Chapter 7. To use those classes now for flat files we must add a prepareOutput method. It is very similar in most classes, but it varies depending on justification and whether or not truncation is allowed. Note again that for flat file formats we need to use only the Length Attribute of the grammar Element, but for EDI support in the next chapter we retrieve the MaxLength Attribute if Length is not present.
DataCellAN prepareOutput Method
For the alphanumeric data type supported by the DataCellAN class, we left-justify and truncate if specified by the Truncatable Attribute of the Grammar Element.
