Method Details
- 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
- updatePosition
  
  protected int updatePosition(int offset, int max_offset)
  
  Called in pass 2 of InstructionList.setPositions() in order to update the branch target, that may shift due to variable length instructions.
  
  Overrides:
  
  updatePosition in class BranchInstruction
  
  Parameters:
  
  offset - additional offset caused by preceding (variable length) instructions
  
  max_offset - the maximum offset that may be caused by these instructions
  
  Returns:
  
  additional offset caused by possible change of this instruction's length
- 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
