In order to save memory you can use some instructions multiply, since they have an immutable state and are directly derived from Instruction. I.e. they have no instance fields that could be changed. Since some of these instructions like ICONST_0 occur very frequently this can save a lot of time and space. This feature is an adaptation of the FlyWeight design pattern, we just use an array instead of a factory.
The Instructions can also accessed directly under their names, so it's possible to write il.append(Instruction.ICONST_0);

You can use these constants in multiple places safely, if you can guarantee that you will never alter their internal values, e.g. call setIndex(). Definition at line 136 of file src/de/fub/bytecode/generic/InstructionConstants.java. |

Interfaces may have no static initializers, so we simulate this with an inner class. Definition at line 159 of file src/de/fub/bytecode/generic/InstructionConstants.java. |
