com.ganteater.ae.MultiClassLoader

Direct Known Subclasses:

JarClassLoader

public abstract class MultiClassLoader
extends 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.

Modifier and Type	Method	Description
protected String	formatClassName(String className)
Class<?>	loadClass(String className)	This is a simple version for external clients since they will always want the class resolved before it is returned to them.
Class<?>	loadClass(String className, boolean resolveIt)
protected abstract byte[]	loadClassBytes(String className)
protected void	monitor(String text)
protected static void	print(String text)
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.
