                              ConstantPool constantPool)

      Parameters:
        `type` - type tag as defined in the Constants interface
        `index` - index to constant pool, or byte code offset

  - ### Method Detail

    - #### copy

          public StackMapType copy()

      Returns:
        deep copy of this object

    - #### dump

          public void dump(DataOutputStream file)
                    throws IOException

      Dump type entries to file.
      Parameters:
        `file` - Output file stream
      Throws:
        `IOException` - if an I/O error occurs.

    - #### getConstantPool

          public ConstantPool getConstantPool()

      Returns:
        Constant pool used by this object.

    - #### getIndex

          public int getIndex()

      Returns:
        index to constant pool if type == ITEM_Object, or offset in byte code, if type == ITEM_NewObject, and -1 otherwise

    - #### getType

          public byte getType()

    - #### hasIndex

          public boolean hasIndex()

      Returns:
        true, if type is either ITEM_Object or ITEM_NewObject

    - #### setConstantPool

          public void setConstantPool(ConstantPool constantPool)

      Parameters:
        `constantPool` - Constant pool to be used for this object.

    - #### setIndex

          public void setIndex(int t)

    - #### setType

          public void setType(byte t)
