Class Icons

java.lang.Object

de.esprit.common.gui.Icons

public class Icons
extends java.lang.Object

This class implements an image/icon cache. The desired icon or image can be requested by a static method and is loaded on demand. Once loaded it is cached in a hash table for reusage.
Note that icons or images are looked up by scanning the CLASSPATH.

This class maintains a missingList which stores failed accesses. This is to avoid accessing the file system repeatedly for a missing icon.
