public class ClassPathLoader

extends java.lang.ClassLoader

Constructor Summary

ClassPathLoader(ClassPath path, java.lang.String name)
A ClassLoader that loads from a ClassPath

Method Summary

ClassPath	getClassPath()
java.net.URL	getResource(java.lang.String name) This cannot easily be implemented under JDK 1.1 (we would have to install our own java.net.URLStreamHandlerFactory but only one is allowed per application so this would not be very modular).
java.io.InputStream	getResourceAsStream(java.lang.String name)
java.lang.Class	loadClass(java.lang.String name, boolean resolve)
byte[]	loadClassData(java.lang.String theClassName)
protected byte[]	loadFromInputStream(java.io.InputStream input, int len)

Constructor Detail

ClassPathLoader

public ClassPathLoader(ClassPath path,
                       java.lang.String name)

A ClassLoader that loads from a ClassPath

Parameters:

path - The path to load from

name - The name of the class loader (just for debugging)

Method Detail

getClassPath

public ClassPath getClassPath()

loadClass

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

Overrides:

loadClass in class java.lang.ClassLoader

getResource

public java.net.URL getResource(java.lang.String name)

This cannot easily be implemented under JDK 1.1 (we would have to install our own java.net.URLStreamHandlerFactory but only one is allowed per application so this would not be very modular). JDK 1.1 supports the jar: protocol for reading entries within JAR files, so this will be easy to implement then.

Overrides:

getResource in class java.lang.ClassLoader

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.String name)

Overrides:

getResourceAsStream in class java.lang.ClassLoader

loadClassData

public byte[] loadClassData(java.lang.String theClassName)
                     throws java.lang.ClassNotFoundException

loadFromInputStream

protected byte[] loadFromInputStream(java.io.InputStream input,
                                     int len)
                              throws java.io.IOException
