A union of items inside a character class set.
The span of the items in this operation. e.g., the a-z0-9
in
[^a-z0-9]
The sequence of items that make up this union.
Push a new item in this union.
The ending position of this union's span is updated to the ending
position of the span of the item given. If the union is empty, then
the starting position of this union is set to the starting position
of this item.
In other words, if you only use this method to add items to a union
and you set the spans on each item correctly, then you should never
need to adjust the span of the union directly.
Return this union as a character class set item.
If this union contains zero items, then an empty union is
returned. If this concatenation contains exactly 1 item, then the
corresponding item is returned. Otherwise, ClassSetItem::Union is
returned.
