Constructor Details
- LoadInstruction
  
  LoadInstruction(short canonTag, short cTag)
  
  Empty constructor needed for Instruction.readInstruction. Not to be used otherwise. tag and length are defined in readInstruction and initFromFile, respectively.
- LoadInstruction
  
  protected LoadInstruction(short opcode, short cTag, int n)
  
  Parameters:
  
  opcode - Instruction opcode
  
  cTag - Instruction number for compact version, ALOAD_0, e.g.
  
  n - local variable index (unsigned short)
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
