[Name] Accessor Return [Used to Create...] For collections: forms, tables, trees, range navigation components, and master-detail widgets For single objects: forms, master-detail widgets, and selection lists For single objects under a constructor: selection lists only [Description] 
Represents an object returned by an accessor method on the business service. An accessor method is used when the objects returned are JavaBeans. Accessor returns appear as children under method returns, other accessor returns, or in the Attributes folder under built-in create methods. Accessor returns are objects that are related to the current object in the parent collection. This relationship is usually based on a common unique attribute in both objects. For example, if a method returns a collection of users, an accessor return that is a child of that collection might be a collection of service requests that are assigned to a particular user. In ADF, the relationship between parent and child collections is called a master-detail relationship. For more information about accessor returns and master-detail objects, see Chapter 8, "Displaying Master-Detail Data". The children under an accessor return may be attributes of the object, other accessor returns, custom methods that return a value from the accessor return, and operations that can be performed on the accessor return.
