Class PageClassLoader

java.lang.Object

java.lang.ClassLoader

fc.web.page.PageClassLoader

public class PageClassLoader
extends ClassLoader

A classloader that loads molly server pages. Each page is loaded by it's own separate ClassLoader.

If a page changes on disk (this is tracked by PageMgr), then the new page is loaded by a new instance of this class. Loaded pages are casted to the non-reloadable Page interface. This Page interface itself is loaded by a parent (typically JVM/system) classloader.
