Examples of org.hotswap.agent.javassist.LoaderClassPath

org.hotswap.agent.javassist.LoaderClassPath
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(). @author Bill Burke @author Shigeru Chiba @see ClassPool#insertClassPath(ClassPath) @see ClassPool#appendClassPath(ClassPath) @see ClassClassPath
