Package	org.puremvc.as3.utilities.loadup
Class	public class Loadup

The Loadup utility (LU) offers a solution to the problem of how to manage the loading of data resources, be that at application startup or at some other time in the duration of the application. By resources, we mean data resources or resources that conform to the resource model adopted by LU. This is the essential LU facility, the kernel, implemented by the classes in the controller, interfaces and model packages. These are independent of the assetloader package, which is an optional sub-system. This kernel is based around the LoadupMonitorProxy class. See that class for the primary documentation of the LU kernel.

The assetloader sub-system offers a solution to the loading of external assets, for example display assets. It uses the LU kernel just as a client application would. The general idea is

there is a group of assets i.e. a set of urls
the group is to be loaded as one loadup task, using a LoadupMonitorProxy instance
each url implies a particular asset type
each asset type maps to a particular asset class and asset loader class
each asset is fronted by an AssetProxy; this proxy implements the LU kernel interface ILoadupProxy and has the asset loader class in a delegate role
the group of assets is fronted by an AssetGroupProxy.

One way to become familiar with this sub-system is as follows

see the AssetTypeMap, AssetFactory and AssetLoaderFactory classes
see the AssetGroupProxy and AssetProxy classes
see the LoadupForAssets demo, as an example use.
