Direct Known Subclasses:

public class DefaultIconSource

implements IconSource

The default implementation of ImageIconRegistry. This implementation caches all icons using soft references (TODO it just lazy loads them, but it doesn't use SoftReference). More specifically, cached icons will remain in memory unless there is a shortage of resources in the system.
