Class ImageIconCache

java.lang.Object

oracle.javatools.util.ImageIconCache

public class ImageIconCache
extends java.lang.Object

An application-wide per-URL cache of ImageIcons.

This class caches instances of ImageIcon using SoftReferences. You should therefore avoid permanently caching the returned icons in your own code, because this could pin icons on the heap unnecessarily.

It is suggested to use this cache wherever an ImageIcon is being constructed in code that may be repetitively or iteratively called. In such cases you may simply replace the code pattern 'new ImageIcon' with 'ImageIconCache.get' to prevent any potential memory leaks or performance overhead from excessive icon creation.
