SmartB2BObject

The SmartB2BObject transforms data between XML and 4GL based on an agreed-upon XML schema mapped to local data representations. It performs this service on behalf of other SmartObjects, particularly the SmartBusinessObject and SmartDataObject.

A single instance transforms either inbound or outbound messages, but not both. Two instances of this object are required when transforming both inbound and outbound messages.

The class name of the object is B2B, and it inherits from classes MsgHandler and XML. All are user-defined classes.

The file src/adm2/b2b.p is the super procedure for the SmartB2BObject class. It contains logic that uses the XML mapping schema to read or store data in data objects. Table 1–6 lists the class and custom files related to b2b.p.

MsgHandler class

The MsgHandler class is represented by the super procedure msghandler.p. Table 1–7 lists the class and custom files related to msghandler.p.

XML class

The Xml.p file presents a simplified DOM API by encapsulating the 4GL DOM statements so that x-noderef handles never need to be exposed to b2b.p. Table 1–8 lists the class and custom files related to xml.p.
