Interface DelegatingClassLoader.ClassFinder

Enclosing class:

DelegatingClassLoader

public static interface DelegatingClassLoader.ClassFinder

This interface is an optimization.

The findClass method of ClassLoader is usually a protected method. Calling loadClass on a ClassLoader is expensive, as it searches the delegation hierarchy before searching in its private space.

Method Summary

Class<?>	findClass(String name)	Finds the class with the specified binary name.
Class<?>	findExistingClass(String name)	Returns the loaded class with the given binary name.
URL	findResource(String name)	Finds the resource with the given name.
Enumeration<URL>	findResources(String name)	Returns an enumeration of URL objects representing all resources with the given name.
ClassLoader	getParent()	Returns the parent class loader.
