States with the same value are equal. 

 public State(int value) 
{
      this(value, null);
}

 public State(int value,
    String name) 
{
      this.value = value;
      this.name = name;
}

 public boolean equals(Object obj) 
{
      if (obj == this) return true;
      if (obj instanceof State) {
         return value == ((State)obj).getValue();
      }
      return false;
}

Check for state equality.

States are considered equal if the integer values of the State objects are equivilent.

 public String getName() 
{
      return (name == null ? String.valueOf(value) : name);
}

Returns the name of the state, or if null returns the integer value as a string.

 public Object getOpaque() 
{
      return opaque;
}

 public int getValue() 
{
      return value;
}

 public int hashCode() 
{
      return value;
}

Returns the has code of the object.

 public  void setOpaque(Object obj) 
{
      opaque = obj;
}

 public String toIdentityString() 
{
      return super.toString();
}

Returns the identity string of this state.

This is the same value returned by Object#toString() .

 public String toString() 
{
      return getName();
}
