Detailed Description

RWDBForeignKeyList is an ordered collection of RWDBForeignKey instances. RWDBForeignKeyList is a relatively low-level construct used by the DB Interface Module as an input/output parameter in the functions RWDBTable::foreignKeys() and RWDBTable::referredToBy().

All RWDBForeignKeyList methods are inherited from RWOrdered. Please see the Essential Tools Module Reference Guide for RWOrdered methods. The only semantics that RWDBForeignKeyList adds to RWOrdered are:

• The index operator operator[]() returns reference to RWDBForeignKey, rather than reference to RWCollectable pointer.
• The destructor deallocates the contents of the RWDBForeignKeyList by calling clearAndDestroy().

Synopsis

 #include <rw/db/forkey.h>
 RWDBForeignKeyList aList;

 aStatus = aTable.foreignKeys( "targetTable", aList);

Returns a reference to the RWDBForeignKey at a position index in self. The call is forwarded to RWOrdered, which throws an exception of type RWBoundsErr if the index is out of range.
