in this example was created cache for images with auto creating new elements for elements that do not present in cache.

		Cache<ImageIcon> imageIconCache = CacheBuilder.create(ImageIcon.class)
			.addConstructor(String.class, Integer.class, Integer.class)
				.set((params) -> {
					Image image = new ImageIcon(ICONS_PATH + params[0]).getImage();
					Image newimg = image.getScaledInstance((Integer) params[1], (Integer) params[2],  java.awt.Image.SCALE_DEFAULT);
					return new ImageIcon(newimg);
				})
			.addConstructor(String.class)
				.set((params) -> new ImageIcon(ICONS_PATH + params[0]))
			.build();

method addConstructor register specific params set and constructor for this set
here is using of created cache:

	imageIconCache.get(filename, width, height);
	imageIconCache.get(filename);
