:) :) sure ...there is nothing that I could not do without extending
dictionary...
with singleTon , I wanted to have the only once reference across the
application ..
I tried once extending it..and ran into a problem..and then solved it by not
sub classing it (directly returning)..
But the curiosity was there in my mind ..hence put up the question here...
Here is the class which i had tried extending dictionary: (though it did not
worked...)
package ms.imfusion.model {
import flash.utils.Dictionary;
import ms.imfusion.Constants;
public class MemberList extend dictionary
{
private static var instance:MemberList; // instance of self.
/**
* property memberList of type Dictionary
*/
public var memberList:Dictionary;
/**
* constructor
*/
public function MemberList(){
super();
}
/**
* Returns the reference to self
*/
public static function getInstance():MemberList {
if(instance == null){
instance = new MemberList();
}
return instance;
}
/**
* Append to memeberlist
* @param tempMember
* @returns void
*/
public function appendtomemelist(tempMember:MemberObject):void {
var userId:int = tempMember.userId;
memberList[userId] = tempMember;
}
/**
* Creating memberlist
* @param obj from server
* creates MemberObject object and adds to memberlist dictionary
* @returns void
*/
public function addToMemberlist(obj:Object):void {
for(var i:int=0;i<obj.length;i++) {
var tempMember:MemberObject = new MemberObject()
tempMember.fill(obj[i]);
appendtomemelist(tempMember);
}
}
/**
*Set instance of memberList null on logout
*/
public static function setInstanceNull():void{
instance = null; // clear mermber information in the current
session
}
}
}
