Class System.ClassLoader

A class loader is responsible for loading class. Its behaviour is quite the same as ClassLoaders in Java, but since this is JavaScript, you need to be very careful of what you are doing.

Basically ZWT defines a system classLoader that should be used to load every classes. Again, this is not Java, there is no use to create a complex classLoader hierarchy.

Classes are asynchronously loaded, it means a class may not be loaded when the loadClass method returns, you should use the System.ClassLoader.ClassLoadListener to monitor classes load.

Defined in: zwt.js.
