                                 throws java.lang.ClassNotFoundException

Generates the class whose descriptor is given, with the given name. The generated class must implement the Generated interface, and its getFcGeneratorParameters method must return classDescriptor.toString(). The default implementation of this method throws an exception.

Parameters:

name - the name of the class to be generated.

classDescriptor - the descriptor of the class to be generated. This descriptor must be of the form "(objectDescriptor arg1 ... argN)" (see loadClass).

loader - an optional class loader to load auxiliary classes.

Returns:

a class named name and whose content is described by the given class descriptor.

Throws:

java.lang.ClassNotFoundException - if a problem occurs during the generation of the class.
