Interface ImageLoader

All Known Implementing Classes:

FileImageLoader

public interface ImageLoader

The ImageLoader interface is meant to serve as a generic method of acquiring images synchrously. The Pong game implements this through the FileImageLoader, that loads images from the file system or class loader resources. It can also serve as a container for serveral images, each stored by a label given to the loadImage() method. When loaded, an Image object can later be retreived by calling getName().
