      `accept` in class `Constant`
    Parameters:
      `v` - Visitor object

    public void dump(DataOutputStream file) throws IOException
    Dump name and signature index to file stream in binary format.
    Specified by:
      `dump` in class `Constant`
    Parameters:
      `file` - Output file stream
    Throws:
      `IOException` - if an I/O error occurs.

    Returns:
      name

  - ### getNameIndex

    public int getNameIndex()
    Returns:
      Name index in constant pool of field/method name.

  - ### getSignature

    public String getSignature(ConstantPool cp)
    Returns:
      signature

  - ### getSignatureIndex

    public int getSignatureIndex()
    Returns:
      Index in constant pool of field/method signature.

  - ### setNameIndex

    Parameters:
      `nameIndex` - the name index of this constant

  - ### setSignatureIndex

    public void setSignatureIndex(int signatureIndex)
    Parameters:
      `signatureIndex` - the signature index in the constant pool of this type
