Interfaces

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 = 'char'

Properties

$codepoint  : int

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.
fromString()  : self
toString()  : string
