org.mule.extension.spring.internal.util.CompositeClassLoader

public class CompositeClassLoader
extends ClassLoader

Classloader implementation that, given a set of classloaders, will first search for a resource/class in the first one. If it is not found, it will try the next and so on until the resource/class is found or all classloaders have been tried.

For getResources(String), all the classloaders will be queried to get the union of all found resources.

Since:

1.0
