Examples of serp.bytecode.Project

serp.bytecode.Project
The Project represents a working set of classes. It caches parsed bytecode and is responsible for bytecode class creation. Currently changes made in one class are not reflected in other classes, though this will be an option in the future.
Bytecode that has been parsed is held in a cache so that retrieving a class with the same name multiple times always returns the same {@link BCClass} instance.
A future goal is to eventually have facilities for traversing jars or directory structures to find classes that meet a given criteria (such as implementing a given interface, etc) and to perform operations on entire projects, similar to aspect-oriented programming.
