    Creates a new empty state set.

  - ### AccessibleStateSet

    public AccessibleStateSet(AccessibleState[] states)
    Creates a new state with the initial set of states contained in the array of states passed in. Duplicate entries are ignored.
    Parameters:
      `states` - an array of `AccessibleState` describing the state set

- ## Method Details

  - ### add

    public boolean add(AccessibleState state)
    Adds a new state to the current state set if it is not already present. If the state is already in the state set, the state set is unchanged and the return value is `false`. Otherwise, the state is added to the state set and the return value is `true`.

  - ### addAll

    public void addAll(AccessibleState[] states)
    Adds all of the states to the existing state set. Duplicate entries are ignored.
    Parameters:
      `states` - `AccessibleState` array describing the state set

  - ### remove

    public boolean remove(AccessibleState state)
    Removes a state from the current state set. If the state is not in the set, the state set will be unchanged and the return value will be `false`. If the state is in the state set, it will be removed from the set and the return value will be `true`.
    Parameters:
      `state` - the state to remove from the state set
    Returns:
      `true` if the state is in the state set; `false` if the state set will be unchanged

  - ### clear

    public void clear()

  - ### contains

    public boolean contains(AccessibleState state)
    Checks if the current state is in the state set.
    Parameters:
      `state` - the state
    Returns:
      `true` if the state is in the state set; otherwise `false`

  - ### toArray

    public AccessibleState[] toArray()
    Returns the current state set as an array of `AccessibleState`.
    Returns:
      `AccessibleState` array containing the current state
