public class D2WQueryToOneRelationship
extends D2WQueryRelationship

The D2WQueryToOneRelationship class is a property-level component that builds a query based on the value for a particular key of a destination object of a to-one relationship. Since the component fetches all of the objects that can appear in the relationship, it is slower than the D2WQueryToOneField component.

Property-level components are not accessed programmatically. Instead, you use the Web Assistant or Rule Editor to choose the property-level component that Direct to Web uses to display a property on a particular entity and task page.

If you want to create a property-level component to query based on a property, use D2WCustomQueryComponent.
