Class SiteSpecificPropertyDerivation

All Implemented Interfaces:

atg.repository.dp.Constants, atg.repository.dp.DerivationMethod, java.io.Serializable

public class SiteSpecificPropertyDerivation
extends atg.repository.dp.DerivationMethodImpl

This derived property method will derive a property based on the current site. For example:

   <property name="feature">
     <derivation user-method="atg.projects.store.dp.SiteSpecificPropertyDerivation">
       <expression>myFeature</expression>
       <expression>siteSpecificFeature</expression>
     </derivation>
   </property>

 where 'myFeature' is a property holding a single 'promotionalContent' 
 repository item and 'siteSpecificFeature' is a Map property holding site specific 
 'promotionalContent' items, i.e. site1=promo1,site2=promo2 etc.
 
 Note that the site specific expression should always be defined after the single value expression.

The derived value or null.
