atom.tuple module

class atom.tuple.FixedTuple(*items, default=None)

Bases: Member

A member which allows tuple values with a fixed number of items.

Items are always validated and can be of different types. Assignment will create a copy of the original tuple before validating the items, since validation may change the item values.

This will clone the internal tuple item if one is in use.

items: Tuple[Member, ...]

set_index(index)

Assign the index to this member.

This method ensures that the item member index is also updated.
