Examples of MultiParentClassLoader

org.apache.axis2.classloader.MultiParentClassLoader
A MultiParentClassLoader is a simple extension of the URLClassLoader that simply changes the single parent class loader model to support a list of parent class loaders. Each operation that accesses a parent, has been replaced with a operation that checks each parent in order. This getParent method of this class will always return null, which may be interpreted by the calling code to mean that this class loader is a direct child of the system class loader. @version $Rev$ $Date$

org.apache.xbean.classloader.MultiParentClassLoader
org.gradle.internal.classloader.MultiParentClassLoader
A {@code ClassLoader} which delegates to multiple parent ClassLoaders.Note: It's usually a good idea to add a {@link CachingClassLoader} between this ClassLoader and anyClassLoaders that use it as a parent, to prevent every path in the ClassLoader graph being searched.
org.gradle.util.MultiParentClassLoader
A {@code ClassLoader} which delegates to multiple parent ClassLoaders.
