implements DXNValueInterface

DXN `symbol` (a bare identifier, e.g. `foo`) -- an unevaluated reference, e.g. a type name. Always wraps: PHP has no "evaluated later" bare-identifier native type, and no interning table whose exhaustion decoding untrusted input would need to guard against either way.

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.

Constants

DXN_TYPE  : mixed = 'symbol'

Properties

$name  : string

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.
