Class SubreportLink

java.lang.Object
com.inet.report.SubreportLink
All Implemented Interfaces:
NodeParser, com.inet.report.ReferenceHolder, Serializable
public class SubreportLink extends Object implements Serializable, com.inet.report.ReferenceHolder, NodeParser
A SubreportLink object links a field in main report with a field in subreport with use of a prompt field in the subreport. The values of the field in main report will used as prompt values in the subreport. These prompt values will be used in the record selection formula to compare with the values of the field in the subreport. The PromptField will be generated automatically, so if you want to use your own PromptField add one to the Fields set and use setPromptField method.

This class is part of the RDC.
