Class BshClassLoader

java.lang.Object

java.lang.ClassLoader

bsh.classpath.BshClassLoader

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Direct Known Subclasses:

DiscreteFilesClassLoader

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.

Constructor Detail

BshClassLoader

public BshClassLoader(BshClassManager classManager,
                      java.net.URL[] bases)

Parameters:

bases - URLs JARClassLoader seems to require absolute paths

BshClassLoader

public BshClassLoader(BshClassManager classManager,
                      BshClassPath bcp)

Parameters:

bases - URLs JARClassLoader seems to require absolute paths

Method Detail

addURL

public void addURL(java.net.URL url)

Overrides:

addURL in class java.net.URLClassLoader

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. An exception is for BeanShell core classes which are always loaded from the same classloader as the interpreter.

Overrides:

loadClass in class java.lang.ClassLoader

Throws:

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

Throws:

java.lang.ClassNotFoundException
