Class ColumnMappingPanel

java.lang.Object
  ca.sqlpower.architect.swingui.ColumnMappingPanel

All Implemented Interfaces:

ca.sqlpower.swingui.DataEntryPanel

public class ColumnMappingPanel
extends java.lang.Object
implements ca.sqlpower.swingui.DataEntryPanel

The ColumnMappingPanel presents a GUI for viewing and modifying the column mappings between two tables. The data model for this panel is a SQLRelationship, and its ColumnMapping children represent the individual mappings from one column to the other. Don't let this fool you into thinking the ColumnMappingPanel can only be used to edit FK relationship mappings, though! You can make a new Relationship, throw it at this editor, then examine its mappings to build up any kind of mapping you want.
