org.apache.beehive.controls.api.properties.PropertyMap
The PropertyMap interface represents a collection of ControlBean properties. Concrete implementations of this interface might derive property values from a local Map, JSR-175 annotation, external configuration, or other property sources.


            // If the returned value is itself a PropertyMap (i.e. a nested annotation type),
            // then wrap it in a PropertySetProxy instance before returning.
            if (value instanceof PropertyMap)
            {
                PropertyMap propertyMap = (PropertyMap)value;
                value = getProxy(propertyMap.getMapClass(), propertyMap);
            }
        }


        return value;
