All Implemented Interfaces:

Closeable

public class CssUrlFilterInputStream
extends BufferedInputStream

filters an input stream of a css file for occurences of "url([classPath])". These image classpaths are then externalized and replaced in the resulting InputStream. This gives us the possibility to load css files and their included images via the classpath, so no external files are needed. If the image is not found at the classpath provided, the occurence is not altered.
