Bytecode Modification Framework

BMF is an alternative JVM bytecode modification framework that (if desired) will hide nothing about the class structure behind abstraction (But in the future abstraction will certainly be an option).

Notable Features

Simplified renaming of classes, fields, and methods
Direct access to the constant pool.

Example: Renaming classes and members

Renaming classes and their members is designed currently to function given a jar file.

Here is an example for renaming a single class and one of its methods.

JarReader read = new JarReader(new File(IN_FILE), true, true);
read.getMapping().getMapping("com/example/game/Edible").name.setValue("com/example/game/Consumable");
read.getMapping().getMapping("com/example/game/Edible").getMemberMapping("isRotten", "()Z").name.setValue("hasDecayed");
read.saveTo(new File(OUT_FILE));

To rename each item takes only a single line of code. The affects of this change are instantaneous across the program since all class names link to a single instance.

What needs finishing

This library is still a heavy WIP and the main focus is remapping classes, so some basic functionality not-pertaining to remapping still needs to be completed. For example there is no way to edit instructions in a method.
