public class BshClassLoader

extends java.net.URLClassLoader

One of the things BshClassLoader does is to address a deficiency in URLClassLoader that prevents us from specifying individual classes via URLs.

protected	BshClassLoader(BshClassManager classManager) For use by children
	BshClassLoader(BshClassManager classManager, BshClassPath bcp)
	BshClassLoader(BshClassManager classManager, java.net.URL[] bases)

void	addURL(java.net.URL url)
protected java.lang.Class	findClass(java.lang.String name) Find the correct source for the class...

Method Detail

addURL

public void addURL(java.net.URL url)

loadClass

public java.lang.Class loadClass(java.lang.String name,
                                 boolean resolve)
                          throws java.lang.ClassNotFoundException

This modification allows us to reload classes which are in the Java VM user classpath. We search first rather than delegate to the parent classloader (or bootstrap path) first.

Overrides:

loadClass in class java.lang.ClassLoader

java.lang.ClassNotFoundException

findClass

protected java.lang.Class findClass(java.lang.String name)
                             throws java.lang.ClassNotFoundException

Find the correct source for the class... Try designated loader if any Try our URLClassLoader paths if any Try base loader if any Try system ???

Overrides:

findClass in class java.net.URLClassLoader

java.lang.ClassNotFoundException
