Create the GeographicalLocationManager and ProductLineManager classes

This scenario assumes that the Manager classes provide the predefined values that are included as extended properties. These values are used in the LetterEditor to display the drop-down values. The classes are defined as follows:

package com.adobe.customizations 
{ 
    import mx.collections.ArrayCollection; 
    import mx.collections.IList; 
 
    public class GeographicalLocationManager 
    { 
        private static var geoInstance:GeographicalLocationManager; 
        public function GeographicalLocationManager() 
        { 
        } 
        //The method is used to retrieve a list of all the available geographical locations 
        public function getAllGeo():IList{ 
            var geos:IList = new ArrayCollection(); 
            geos.addItem(""); 
            geos.addItem("Africa"); 
            geos.addItem("Asia Pacific"); 
            geos.addItem("Europe"); 
            geos.addItem("Latin America"); 
            geos.addItem("Middle East"); 
            geos.addItem("North America"); 
            return geos; 
        } 
        public static function getInstance():GeographicalLocationManager{ 
            if(geoInstance == null) 
                geoInstance = new GeographicalLocationManager(); 
            return geoInstance; 
        } 
    } 
} 
 
package com.adobe.customizations 
{ 
    import mx.collections.ArrayCollection; 
    import mx.collections.IList; 
 
    public class ProductLineManager 
    { 
        private static var prodLineInstance:ProductLineManager; 
        public function ProductLineManager() 
        { 
        } 
        //The method is used to retrieve a list of all the available product lines 
        public function getAllProductLines():IList{ 
            var prodLines:IList = new ArrayCollection(); 
            prodLines.addItem(""); 
            prodLines.addItem("Medical Insurance"); 
            prodLines.addItem("Property Insurance"); 
            prodLines.addItem("Vehicle Insurance"); 
            prodLines.addItem("Travel Insurance"); 
            prodLines.addItem("General Insurance"); 
            return prodLines; 
        } 
        public static function getInstance():ProductLineManager{ 
            if(prodLineInstance == null) 
                prodLineInstance = new ProductLineManager(); 
            return prodLineInstance; 
        } 
    } 
}
