Constructor Detail

### LDC

    public LDC(int index)

Method Detail

### setSize

    protected final void setSize()

### dump

    public void dump(DataOutputStream out)
              throws IOException

  Dump instruction as byte code to stream out.

  Overrides:
    `dump` in class `CPInstruction`
  Parameters:
    `out` - Output stream
  Throws:
    `IOException`

### setIndex

    public final void setIndex(int index)

  Set the index to constant pool and adjust size.

  Specified by:
    `setIndex` in interface `IndexedInstruction`
  Overrides:
    `setIndex` in class `CPInstruction`
  Parameters:
    `index` - in constant pool.

### initFromFile

    protected void initFromFile(ByteSequence bytes,
                                boolean wide)
                         throws IOException

  Read needed data (e.g. index) from file.

  Overrides:
    `initFromFile` in class `CPInstruction`
  Parameters:
    `bytes` - input stream
    `wide` - wide prefix?
  Throws:
    `IOException`

### getValue

    public Object getValue(ConstantPoolGen cpg)

### getType

    public Type getType(ConstantPoolGen cpg)

  Specified by:
    `getType` in interface `TypedInstruction`
  Overrides:
    `getType` in class `CPInstruction`
  Returns:
    type related with this instruction.

### getExceptions

    public Class[] getExceptions()

  Specified by:
    `getExceptions` in interface `ExceptionThrower`

### 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
