  - dump
```
public void dump(java.io.DataOutputStream out)
          throws java.io.IOException
```
    Dump instruction as byte code to stream out.
    
    Overrides:
    
    dump in class CPInstruction
    
    Parameters:
    
    out - Output stream
    
    Throws:
    
    java.io.IOException
  - getExceptions
```
public java.lang.Class<?>[] getExceptions()
```
  - 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
