findClass

public java.lang.Class findClass(java.lang.String name)
                          throws java.lang.ClassNotFoundException

Description copied from class: java.lang.ClassLoader

Called for every class name that is needed but has not yet been defined by this classloader or one of its parents. It is called by loadClass() after both findLoadedClass() and parent.loadClass() couldn't provide the requested class.

The default implementation throws a ClassNotFoundException. Subclasses should override this method. An implementation of this method in a subclass should get the class bytes of the class (if it can find them), if the package of the requested class doesn't exist it should define the package and finally it should call define the actual class. It does not have to resolve the class. It should look something like the following:

 // Get the bytes that describe the requested class
 byte[] classBytes = classLoaderSpecificWayToFindClassBytes(name);
 // Get the package name
 int lastDot = name.lastIndexOf('.');
 if (lastDot != -1)
   {
     String packageName = name.substring(0, lastDot);
     // Look if the package already exists
     if (getPackage(packageName) == null)
       {
         // define the package
         definePackage(packageName, ...);
       }
   }
 // Define and return the class
  return defineClass(name, classBytes, 0, classBytes.length);
 

loadClass() makes sure that the Class returned by findClass() will later be returned by findLoadedClass() when the same class name is requested.

getResourceAsStream

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

Description copied from class: java.lang.ClassLoader

Get a resource as stream using this classloader or one of its parents. First calls getResource() and if that returns a URL to the resource then it calls and returns the InputStream given by URL.openStream().

Subclasses should not override this method but should override findResource() which is called by this method.

loadClassData

private byte[] loadClassData(java.lang.String name)
                      throws java.lang.ClassNotFoundException

setProgressListener

public void setProgressListener(ProgressListener listener)

---

fireProgressListener

private void fireProgressListener(ProgressEvent event)
