  - getType
```
public Type getType(ConstantPoolGen cp)
```
    Specified by:
    
    getType in interface TypedInstruction
    
    Returns:
    
    Type.NULL
  - accept
```
public void accept(Visitor v)
```
    Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.
    
    Specified by:
    
    accept in class Instruction
    
    Parameters:
    
    v - Visitor object
