Constructor Details

BshClassLoader

public BshClassLoader(BshClassManager classManager,
 URL[] bases)

Parameters:

bases - URLs JARClassLoader seems to require absolute paths

BshClassLoader

public BshClassLoader(BshClassManager classManager,
 BshClassPath bcp)

Parameters:

bcp - BshClassPath from which we'll take our base URLs

BshClassLoader

protected BshClassLoader(BshClassManager classManager)

For use by children

Method Details

addURL

public void addURL(URL url)

Overrides:

addURL in class URLClassLoader

loadClass

public Class loadClass(String name,
 boolean resolve)
                throws 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 ClassLoader

Throws:

ClassNotFoundException

findClass

protected Class findClass(String name)
                   throws 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 URLClassLoader

Throws:

ClassNotFoundException
