Using XML with Legacy Business Applications

DataCell Base Class

Overview

This class is the base for all the classes we use to represent the various data types. With a few minor variations, for each specific data type that we support in a non-XML format we provide a derived class that handles converting that type to and from the corresponding Schema data type.

Attributes:

• Byte or Character Array Cell Buffer

• DOM Element Field Grammar

• Integer Buffer Length

• Integer Field Number

• Integer Subfield Number
