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).

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

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.

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.
