DXNDuration

• Application

implements DXNValueInterface

DXN `duration` (`@duration "P1Y2M"`) -- 7 independent, individually optional fields, not reducible to one scalar. No conversion helper: PHP's `DateInterval` exists, but normalizes `P1W` into `days = 7` internally, losing the weeks/days distinction DXN keeps independent -- not a clean conversion target.

DXNValueInterface

Implemented by every `DXN*` wrapper class -- the PHP analog of the `dxnType` string tag used for kind dispatch in the JS port, and of `Dextrin.Value`'s closed type union in the Elixir original. Native PHP values (`null`, `bool`, `int`, `float`, `string`, and `array` for `map`/`array`) never implement this; {@see Equality::kindOf()} handles those directly.

Methods

__construct()  : mixed

compareTo()  : int

A total order against any other DXN value, not just another instance of this class -- backs {@see DXNSortedSet}. Cross-kind ordering is implementation-defined per DXN.md; within a kind, uses the kind's own natural order where one exists, or a deterministic structural fallback where it doesn't.

dxnType()  : string

The DXN type name this value represents, e.g. "symbol", "uuid".

equals()  : bool

Structural equality, recursing into nested DXN values as needed.
