javax.rad.model.reference
Class StorageReferenceDefinition

java.lang.Object
  javax.rad.model.reference.ColumnMapping
      javax.rad.model.reference.StorageReferenceDefinition

All Implemented Interfaces:

Serializable, Cloneable

public class StorageReferenceDefinition
extends ColumnMapping

The StorageReferenceDefinition specifies the relation between a detail IStorage and the master IStorage.
It also can be used as "server side" binding between a drop down list (with an list of items to choose from) and the corresponding "master" DataBook to write the defined item (e.g. PrimaryKey columns to ForeignKey columns) back to it.

Example:

 
 StorageReferenceDefinition bdDETAILtoTEST = new StorageReferenceDefinition();
 bdDETAILtoTEST.setReferencedStorage("test");
 bdDETAILtoTEST.setReferencedColumns(new String [] { "ID" });
 bdDETAILtoTEST.setColumns(new String [] { "TEST_ID" });
