  • Constructor Details

    • RET

      public RET(int index)

  • 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 Instruction
      Parameters:
      out - Output stream
      Throws:
      IOException - Thrown when an I/O exception of some sort has occurred.

    • getIndex

      public final int getIndex()
      Specified by:
      getIndex in interface IndexedInstruction
      Returns:
      index of local variable containg the return address

    • getType

      public Type getType(ConstantPoolGen cp)
      Specified by:
      getType in interface TypedInstruction
      Returns:
      return address type

    • initFromFile

      protected void initFromFile(ByteSequence bytes, boolean wide) throws IOException
      Read needed data (e.g. index) from file.
      Overrides:
      initFromFile in class Instruction
      Parameters:
      bytes - byte sequence to read from
      wide - "wide" instruction flag
      Throws:
      IOException - may be thrown if the implementation needs to read data from the file

    • setIndex

      public final void setIndex(int n)
      Sets index of local variable containg the return address
      Specified by:
      setIndex in interface IndexedInstruction

    • toString

      public String toString(boolean verbose)
      Description copied from class: Instruction
      Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"
      Overrides:
      toString in class Instruction
      Parameters:
      verbose - long/short format switch
      Returns:
      mnemonic for instruction
