Examples of CodeIterator

javassist.bytecode.CodeIterator
An iterator for editing a code attribute.
If there are multiple CodeIterators referring to the same Code_attribute, then inserting a gap by one CodeIterator will break the other CodeIterator.
This iterator does not provide remove(). If a piece of code in a Code_attribute is unnecessary, it should be overwritten with NOP. @see CodeAttribute#iterator()
org.jboss.forge.furnace.proxy.javassist.bytecode.CodeIterator
An iterator for editing a code attribute.
To directly read or edit a bytecode sequence, call {@link #byteAt(int)}, {@link #s16bitAt(int)}, {@link #writeByte(int,int)}, {@link #write16bit(int,int)}, and other methods. For example, if method refers to a CtMethod object, the following code substitutes the NOP instruction for the first instruction of the method:
```
 CodeAttribute ca = method.getMethodInfo().getCodeAttribute(); CodeIterator ci = ca.iterator(); ci.writeByte(Opcode.NOP, 0);
```
To visit every instruction, call {@link #next()} on a CodeIterator.It returns the index of the first byte of the next instruction.
If there are multiple CodeIterators referring to the same Code_attribute, then inserting a gap by one CodeIterator will break the other CodeIterator.
This iterator does not provide remove(). If a piece of code in a Code_attribute is unnecessary, it should be overwritten with NOP. @see CodeAttribute#iterator()
