Enclosing class:

ImageCache

public abstract static class ImageCache.ImageCreator

extends java.lang.Object

This class holds an image with a soft reference to it. The class is abstract, because the first time - or after removing the image from the cache - the image must be (re)created. This must be done by the {@link #createImageIcon() method.
