      Parameters:
        `index` - the object index.
        `object` - the object (`null` permitted).

    - #### clear

          public void clear()

      Clears the list.

    - #### size

          public int size()

      Returns the size of the list.
      Returns:
        The size of the list.

    - #### indexOf

          protected int indexOf(java.lang.Object object)

    - #### equals

          public boolean equals(java.lang.Object obj)

      Tests this list for equality with another object.
      Overrides:
        `equals` in class `java.lang.Object`
      Parameters:
