  - getStackChange
```
public int getStackChange()
```
    Description copied from class: Instruction
    
    Return the number of stack positions this instruction pushes or pops during its execution.
    
    Overrides:
    
    getStackChange in class Instruction
    
    Returns:
    
    0 if the stack is not affected by this instruction, a positive number if it pushes onto the stack, and a negative number if it pops from the stack
  - getLength
```
int getLength()
```
    Description copied from class: Instruction
    
    Return the length in bytes of this opcode, including all arguments. For many opcodes this method relies on an up-to-date byte index.
    
    Overrides:
    
    getLength in class Instruction
  - setOffset
```
public void setOffset(int offset)
```
    Overrides:
    
    setOffset in class JumpInstruction
  - calculateOpcode
```
private void calculateOpcode()
```
    Calculate our opcode based on the offset size.
