  - ### ConstantInvokeDynamic

    public ConstantInvokeDynamic(ConstantInvokeDynamic c)
    Initialize from another object.
    Parameters:
      `c` - Source to copy.

  - ### ConstantInvokeDynamic

    public ConstantInvokeDynamic(int bootstrapMethodAttrIndex, int nameAndTypeIndex)
    Constructs a ConstantInvokeDynamic.
    Parameters:
      `bootstrapMethodAttrIndex` - Index to the bootstrap method.
      `nameAndTypeIndex` - Index to the name and type.

- ## Method Details

  - ### accept

    public void accept(Visitor v)
    Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.
    Specified by:
      `accept` in interface `Node`
    Specified by:
      `accept` in class `Constant`
    Parameters:
      `v` - Visitor object.

  - ### getBootstrapMethodAttrIndex

    public int getBootstrapMethodAttrIndex()
    Gets the reference (index) to bootstrap method this constant refers to.
    Returns:
      Reference (index) to bootstrap method this constant refers to. Note that this method is a functional duplicate of getClassIndex for use by ConstantInvokeDynamic.
    Since:
      6.0

  - ### toString

    public String toString()
    Overrides:
      `toString` in class `ConstantCP`
    Returns:
      String representation.
