|

* <p>
|
||||
* The format of the disassembled bytecode includes the opcodes
|
||||
* (in the form of mnemonics such as "ILOAD") and all the operands.
|
||||
* Some operands can be printed as simple integers, while others have to be printed in a more understandable form
|

* (e.g. method or field names and descriptors).
|

* Operands of branch instructions are shown as an "id" of the targeted instruction.
|
||||
* For this, all instructions of a method, including ASM's pseudo-instructions (LABEL, LINE, FRAME),
|
||||
* are numbered, starting at 0.
|
