Constructor Details
- JSR_W
  
  JSR_W()
  
  Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.
- JSR_W
  
  public JSR_W(InstructionHandle target)
Method Details
- 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
- dump
  
  public void dump(DataOutputStream out) throws IOException
  
  Dump instruction as byte code to stream out.
  
  Overrides:
  
  dump in class BranchInstruction
  
  Parameters:
  
  out - Output stream
  
  Throws:
  
  IOException - Thrown when an I/O exception of some sort has occurred.
- initFromFile
  
  protected void initFromFile(ByteSequence bytes, boolean wide) throws IOException
  
  Read needed data (e.g. index) from file.
  Overrides:
  
  initFromFile in class BranchInstruction
  
  Parameters:
  
  bytes - input stream
  
  wide - wide prefix?
  
  Throws:
  
  IOException - may be thrown if the implementation needs to read data from the file
