- - ### Constructor Detail

    - #### ConstantDynamic

          public ConstantDynamic(ConstantDynamic c)

      Initialize from another object.

    - #### ConstantDynamic

          public ConstantDynamic(int bootstrap_method_attr_index,
                                 int name_and_type_index)

  - ### Method Detail

    - #### 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 final int getBootstrapMethodAttrIndex()

      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 final String toString()

      Overrides:
        `toString` in class `ConstantCP`
      Returns:
        String representation
