JarClassLoader

public abstract class MultiClassLoader

extends java.lang.ClassLoader

A simple test class loader capable of loading from multiple sources, such as local files or a URL.

This class is derived from an article by Chuck McManis http://www.javaworld.com/javaworld/jw-10-1996/indepth.src.html with large modifications.

Note that this has been updated to use the non-deprecated version of defineClass() -- JDM.

Constructor Summary

MultiClassLoader()

Method Summary

protected java.lang.String	formatClassName(java.lang.String className)
java.lang.Class	loadClass(java.lang.String className) This is a simple version for external clients since they will always want the class resolved before it is returned to them.
java.lang.Class	loadClass(java.lang.String className, boolean resolveIt)
protected abstract byte[]	loadClassBytes(java.lang.String className)
void	setClassNameReplacementChar(char replacement) This optional call allows a class name such as "COM.test.Hello" to be changed to "COM_test_Hello", which is useful for storing classes from different packages in the same retrival directory.

Method Detail

loadClass

public java.lang.Class loadClass(java.lang.String className)

This is a simple version for external clients since they will always want the class resolved before it is returned to them.

Overrides:

loadClass in class java.lang.ClassLoader

loadClass

public java.lang.Class loadClass(java.lang.String className,
                                 boolean resolveIt)
                          throws java.lang.ClassNotFoundException

Overrides:

loadClass in class java.lang.ClassLoader

setClassNameReplacementChar

public void setClassNameReplacementChar(char replacement)

This optional call allows a class name such as "COM.test.Hello" to be changed to "COM_test_Hello", which is useful for storing classes from different packages in the same retrival directory. In the above example the char would be '_'.

loadClassBytes

protected abstract byte[] loadClassBytes(java.lang.String className)

formatClassName

protected java.lang.String formatClassName(java.lang.String className)
