Flash As3 Game: Class Question

Question

I'm making a game in as3 using flash develop and flash cs5. Everything is object oriented. I was wondering, should I have one "gateway" class that has a property-reference to all instantiations of other classes, and I just pass this gateway class to new objects, so they have access to every class. Like so:

 var block:Block = new Block(gateway);

 //In the block class:
 this.gateway.player.setHealth(100);
 //Or:
 this.gateway.input.lock();

Is this like a singleton pattern or something? Should I do this?

I've used this idea before. I used it as a model. the dataModel - or an effective backbone of which dumb stores your objects - or references to your objects. This is useful as you can always find something without walking through your classes.

I've used it as a singleton - therefore you have no fear of potentially creating a new version of your dataModel and references blank objects. Kinda stops you scratching your head for hours. It would look something like this:

package com.strangemother.models.DataModel
{
    private static var _dataModel:DataModel;
    /**
    an example of storing you items.
    */
    public var character:Character;

    public static function getInstance():DataModel
    {


     if(!_dataModel)
        {
  _dataModel= new DataModel(SingletonLock); 
  return _dataModel;

     }

 public function DataModel(lock:Class)
 {
  if(!lock is SingletonLock)
  {
   throw new Error("DataModel is a singleton. Use DataModel.getInstance() to use.");
  }
 }
}

this is a one ( 1 ) this is the letter L lowercase ( l )
