javassist.LoaderClassPath
All Implemented Interfaces:
ClassPath
public class LoaderClassPath extends Object implements ClassPath
A class search-path representing a class loader.

It is used for obtaining a class file from the given class loader by getResourceAsStream(). The LoaderClassPath refers to the class loader through WeakReference. If the class loader is garbage collected, the other search pathes are examined.

The given class loader must have both getResourceAsStream() and getResource().

Class files in a named module are private to that module. This method cannot obtain class files in named modules.
